.300 AAC Blackout - 'Enabling' Thread (Mags, ammo, optics, barrels, etc.)

I wish I had seen these (https://www.primaryarms.com/lancer-20rd-smoke-cosmetic-blem-magazine?trk_msg=V8J31UP5DHGKP94AK0TT6LI2G8&trk_contact=3LMOB4NHK40RBGEM6R89MNTHOO&trk_module=arm&trk_sid=F5RDIT4UEGI8FQ15NHV3OSJJR0&utm_source=listrak&utm_medium=email&utm_term=Shop+Now&utm_campaign=Recurring-Automated-Campaign&utm_content=Recurring-Automated-Campaign) before ordering the full-price ones.

So best mags for .300BLK?

I've heard Lancer 20-rounders and 3rd Gen PMAG 30-rounders?

[OlongJohnson]

Seems some Academy stores have some UMC .300 BLK available if you're willing to brave the covids and go in person to pick it up. Price is about even with the best online sellers, who are all sold out anyway.

Sure do wish I'd know I'd get sucked down this rabbit hole back in November/December when Walmart was dumping all its evil "assault weapon" ammo for half price.

[LittleLebowski]

I like Lancer 20s.

I just put together a cheap poor mans 300 BO. So far, I love it. Very easy to shoot and fun.

I have a spare rifle lower I should build into something. Since I’m planning to take the .300Blk plunge - I’m considering a 16” upper.

Lancers are best for subsonic, but I find that supersonics seem to work well out of any mag with Magpul followers.

NOTE: These magazines are optimized for subsonic 300BLK ammunition which have a wider and more forward-oriented ogive on the projectile. If you are shooting lightweight supersonic 300BLK ammunition (<150gr), we recommend using a standard .223/5.56 magazine, as the geometry of most supersonic cartridges more closely mimics that of a .223/5.56 cartridge.

https://lancer-systems.com/product/l5awm-300blk-20-magazine/


Specifically engineered for use with heavy subsonic .300 Blackout ammunition (200+ grain), the Lancer L5AWM® 300BLK magazine features an updated internal geometry which allows longer heavier cartridges to stack properly, increasing feeding reliability when compared to a traditional .223/5.56 magazine. The outside of the mag body is molded with distinctive .300 Blackout markings and the magazine ships with a contrasting flat dark earth floor plate for easy visual identification.

Anybody run the Hornady 190 subs yet? I'm mostly going to be sticking with supers, and am OK with selecting the long, skinny ones designed for feeding .300 BLK in 5.56 mags, but if the Hornadys work better with a specific mag, I'll probably pick up a couple Magpuls or Lancers.

So far, I have some Tac-TX 110s and some UMC 120s (bullet also made by Barnes, at least originally).

Not components, just loaded ammo. Academy seems to still have them in several of the stores around here at not-usurious prices. Limit five boxes/customer.

Managed to pick up a box of V-Max 110s to load and a box of .309 90gr XTPs, which I think should work well for single-shot varmint duty. The rest of my resupply plan is to wait for some 125gr TNTs to come available.

Same.

I use Lancers exclusively for .300 to help avoid any cross pollination with 5.56 since it both looks and feels different than the GI and Magpul mags I use for 5.56.

Interesting comment on the Hornady 190s in a non-gas gun here:

http://www.300blktalk.com/forum/viewtopic.php?f=137&t=108093&start=10#p1002737


I have a Howa 1500 , 16" 300 Blackout. I reload 100gr , 130, 150 and 167gr subs, all for around 1030-1050 .
Those 190's were the first ones I tried. They were LOUD like a cannon.
You can make reloads that are about half as loud with less gaseous powders.
Commercially available subs need to cycle auto's. Bolt doesn't need that so you can use alot quieter powders.

They are well-suited to .300 BLK and less than 2/3 the cost of any similar bullet from Hornady, Sierra, etc. With the 20 percent off rebate that ended 4/30, they could be down in the $0.14/rd range if you could find them in stock. Other places list the 500 packs under $70, but haven't had inventory in the weeks I've been looking. With free shipping, that makes them $0.14/rd without a rebate, ~$0.11 if you could have gotten on the rebate. Hornady SSTs don't get much under $0.28/rd, Sierras are ~$0.30-0.34/rd.

How do they shoot out to 100-150?
Are you running them with a suppressor attached?
Are they reasonably clean?
Does the coating cause additional smoke?

Thanks. Did these guys acquire Leather Head projectiles? I notices the name on the golden brown variant and am wondering because i couldn't find Leather Head anymore when I looked for them a bit back.

[Norville]

This is apparently one of the best defensive loads, and not cheap or readily available at the moment. Midway has it at that the going rate, and free shipping if you spend $49 which is like a box and a half :D

[OlongJohnson]

I assume you're talking about this?

https://www.targetsportsusa.com/barnes-vor-tx-300-aac-blackout-ammo-110-gr-tipped-tac-tx-fblf-21548-p-4401.aspx

You'll save some over Midway if you wait a little while for TSUSA to get it back.

If you're talking just components, the #30362, 110gr TTSX is definitely NOT the same as the #30321, 110gr Tac-TX. The latter is specially designed to expand reliably at .300 BO short barrel speeds, down to ~1300 FPS as I recall.

I had a CompM5 on it mounted in a Scalarworks mount then switched it to a lrp mount I had sitting around. Then I saw a Sig Romeo 5 (https://www.amazon.com/Sig-Sauer-SOR50000-Romeo5-Compact/dp/B07T9GK7SR) on sale for dirt cheap and figured I’d give that a try. I don’t have many rounds through it but the dot is actually a little more crisp than an Aimpoint I don’t know why but it is. It’s also a slimmer housing which I like but you could get the same in an H or T series Aimpoint.

I’m interested to play with one of the romeos. Some friends have had good luck with the Vortex crossfire T-1 knockoff so I sort of consider that the best budget red dot, but I’m SIG curious these days. I definitely would not run irons on anything that had the potential to be put into service.

Okay, I'll check out the Romeo5.

I'm still seriously considering the Primary Arms/Holosun HS503G with the ACSS reticle. - https://www.primaryarms.com/holosun-paralow-hs503g-red-dot-sight-acss-reticle

The fact that they have kind of figured out the BDC for a 50-yard zero with .300BLK super and subs - if my supers and subs hit close to the same at 50 - I should be able to swap ammo without needing a different zero. I can probably zero at 25 and figure out how close the BDC dots are at other distances with subs and supers. The good news is - at 25 the subs and supers shouldn't be different POI pretty much at all.

Plus the horseshoe should work nice for a hold-over at close range. Though I don't know how much hold-over will be needed with a 5.5" Rattler.

With something as short as the rattler and the loss in velocity this might not work but...if you send 125s out at around 2050fps and zero at 25-27yrds that gives you a 50yrd zero with subs @~1050fps. The ~25 yrd super zero gives you a second at ~200 yrds according to jbm ballistics. I haven’t tested the second zero, but the ~25yrd super/50yrd sub checks good from my 8-9” barrels.

I’m not convinced that this is the best super zero, but with a single dot, it is the only thing I have found that works.

No way you'd get 2050 from the 5.5" barrel in a 125gr pill. The 110's max will run around 1800 fps. But I agree that they likely won't coalesce if they do the distances will be odd. Still one could likely make things work by playing with the zero distance a bit and make it usable.

I don’t have one to test, my shortest is 8”. I can try running some numbers through the calculator to see what works. Has anybody actually chrono’d anything out of the rattler?

ETA: I ran some numbers and at 1800 FPS, it looks like the super zero would be in the same range with the second zero moving to around 150 yrds. It might me worth testing.

I've run some load data through QuickLoad, it's the same load as when I worked up 110 Barnes for several 300 Blackout carbines ranging from 8.5-9.5. The load was within 30-40 fps once I had chronographed them so it will be close. QL shows from a 5.5" barrel, 18.5gr Lil'Gun, trim length 1.367" and a OAL of 2.250" at 1,805 fps ATM. PSI reading is really near max at 49,791 PSI so flattened primers for certain, pretty much the peak of what you can expect. I will get readings this weekend for the Rattler with a few different loads and the .32 NAA barrel I just picked up for the LCP. I will certainly post everything once I have a minute to get them. I wish I had some of the Sig stuff but I'll just have to settle for what I have which is some HDY Black 110's, Barnes 110's, AMAX 208's and the 190 SUB-X. I think I also have some of the Magtech Tactical 110gr stuff left over but it might be something else.

They also have the SIG SBR 120’s a bit cheaper than from sig directly but it’s not significant once you factor the free shipping from SIG.

I’m liking the availability of the SIG duty stuff. The Barnes scavenger hunt is fine while locked down and bored but once life gets back to normal that’s annoying. If the reports on it are good I may eventually switch for serious purpose ammo.

[entropy]

I’ve been running the 503 with a removable Vortex 3X magnifier since I built the upper. I’m very happy with it. The magnifier can be swung aside or quickly removed altogether. I keep a small cut-off box wrench in the grip. It gives me the versatility of keeping the magnifier off if I’m using it as a travel/truck gun, or mounting it up if I’m out in the woods or sighting in for accuracy.

Is H110 the preferred powder? .300 BO is probably going to force me to get off my ass to reload... ammo prices are not what I like to see haha.

H110 is definitely one of the top choices for supersonics. Handloading these on a single stage is slow, but at least H110 meters fast.

I don’t plan on shooting 300BLK that much.

Another thing about H110 is lots of folks that reload have it around already, because it delivers top velocities in 357mag and 44mag. It even covers .410 if that floats your boat. :cool:

Are there preferred powders for subs? Anyone have a resource for vetted reloading recipes?

Accurate 1680 is my go to for subs. There are others that work though. Pretty much all the reloading books have sub info now, but most are for 16” barrels. You will probably have to tweak them to get your desired velocity.

[Grey]

So has anyone compared the Barnes 110 vs the 120? The 110 seems to be the go to round - does the 120 not perform as well?

[OlongJohnson]

It eats up more case volume, so max powder charges are smaller. You end up with velocities so much lower that even with the higher BC on the 120, the 110 carries more energy out to a range where you might reconsider the appropriateness of the cartridge. I haven't run numbers myself, but that's the gist of discussion I've seen.

OTOH, I think the 120 is an excellent candidate for reduced loads in a .308 or single-shot (because the tips are a no-go in a tube mag) .30-30.

I don’t know about terminal performance, but velocity wise I can get ~2290 FPS with the 110s and ~2030 with the 120s out of a SR30. The 110s are running pretty hot though based on looking at the primers, but the 120s aren’t far behind.

Where'd we land on acceptable supersonic defensive ammo?

Definites:

110-grain Barnes Tac-TX
120-grain Sig Solid Copper - Either the Elite OTM or the SBR Solid
110-grain Hornady GMX

Unsure:

110-grain Hornady VMax
135-grain Hornady FTX
120-grain Fiocchi SST

___

Seems like the unsure are all lead-core bullets and I'm wondering if they are going to expand at all at lower velocity from a short barrel gun?

___

For subsonic -

Hornady 190-grain Sub-X
Sig 205-grain Subsonic Tipped*

*Sig Recommends at least 9" barrel for this load.

Hornady has tested the Sub-X down to an 8" barrel and it's only losing about 9 fps over a 16" barrel (1041 in 8", 1050 in 16"). So, it should be fine.

Pistol:

Rifle:

.300BO supers and subs
.30-30Win supers

Regardless, I don’t think there is a powder that will cover all of those, unless we’re talking like massive download Trailboss or somethIng.

I’m leaning towards SBR-SOCOM for .300BLK. It’s newer, but a lot of good reports and wide range of load data for different bullet weights. It burns faster than H110 - so maybe a bit more consistent in a Rattler. It’s also good for heavy subs, like 1680 (burns a tad slower than 1680). Maybe I can generate enough pressure to reliably cycle the action with subs.

It seems only a few bullets work well with 300. The all copper, designed specifically for the caliber, is what I’d use for defense. Everything else is just a quest to get good functioning training ammo. The TNTs seem to hit the right spot for cost and function.

We talked about a bolt gun somewhere. Stumbled upon this option.

AAC barrel for Seven/700 for $150. It appears to be the barrel used on factory Model Seven rifles chambered in .300 BLK.

https://www.cdnnsports.com/remington-7-700-300-blackout-threaded-barrel-aac.html#.Xsngi2hKiHs

Add it to an inexpensive .223 receiver (maybe you have an unused one sitting around) or just a receiver only https://gun.deals/search/apachesolr_search/047700273471 and off you go.

I'd probably wait until Magpul releases its AICS-compatible mag for 5.56 later this year and throw it in a Hunter stock.

https://magpul.com/firearm-accessories/pmags/bolt-action/pmag105-56ac.html

Sez: "Accepts cartridge overall length (COAL) of up to 2.39”."

That's actually a pretty compelling setup vs. the Howa. Would end up running more than the Ruger American if you go the Magpul route, but you'd have a pretty nice stock.

Awesome, I came across 10 brand new 20-round Thermolds this evening when I was moving a box of stuff in my storage unit. Nothing quite like opening a box and finding some gold. I dunno when I bought these, probably 2012’ish, when I think CDNN had them for 4-bucks a piece.

I shoot a lot of 3/4oz 20g loads for skeet and there are not a lot of listed loads for that, having International around in significant amounts, that only does one thing, bugs me :cool:

Heck of a time to sell right now if you decide to. Use the advanced search on GB and look for closed auctions. I find sorting by highest number of bids first usually brings up the actual sales effectively. I don't know any particulars of that setup, but my instinct is the prices you saw were brand fanboy buyers. It's quite possible that twist rates, gas port sizing, and rails have all advanced since it was the hotness. I'd want a shorter barrel myself.

Pistol-cartridge barrels are generally rifled with twist rates several times longer than a typical pistol barrel and it doesn't impair their accuracy. Would a J frame snubby be improved in any way if the twist changed from whatever it is (1:18, maybe) to 1:2?

I have the same upper, it has been one of the best performing 300 blk s I have used. Good accuracy and no issues with function (sub or super). They had blow out pricing on these years ago, which is when I bought it.

[El Cid]

Pistol-cartridge barrels are generally rifled with twist rates several times longer than a typical pistol barrel and it doesn't impair their accuracy. Would a J frame snubby be improved in any way if the twist changed from whatever it is (1:18, maybe) to 1:2?

It's hardly nonsense. He asked specifically about 300BLK in 8 to 8.5" bbls. My comments about twist rate were to his specific question. With an 8" bbl in 300BLK a twist rate that of 1/7 is good to go. A 1/9 or slower would not stabilize the bullet.

I have no idea why you are talking about 16" bbls or J-frames...

[OlongJohnson]

The twist rate that is appropriate for a given cartridge and loading is almost completely independent of barrel length (significant differences in barrel length leading to increased velocity when playing with marginal stability can make a difference, but that's not relevant to .300 BLK short barrels), so to state the required twist in terms that implies there's something important or even related about the bullet making a complete rotation while it's in the bore is misleading. 1:7 or 1:8 is an appropriate twist for .300 BLK (assuming subs will eventually be used, at some point on somebody's part) whether the barrel is 5.5 inches or 16 or 20 inches.

The way you stated it could be interpreted as:
If you have a 9-inch barrel, then 1:9 twist is good.
If you go with an 8-inch barrel, you need to tighten up to 1:8.
If you go down to a 7-inch barrel, you better make sure it's a 1:7 twist.

Which is not how it works.

Yeah, I should've been more clear -- I checked GB and there aren't any AAC 9" uppers or complete 9" MPW rifles for sale, either currently or in the completed listings. Only the 12.5 and 16"ers.

But I think you're right about the next panic; I'm gonna cash out on an NOS Colt Socom II rifle for sure then, maybe a second Socom II upper, and maybe this AAC also. I think I'll stand to double or triple my $$ that way.

If you have a 9-inch barrel, then 1:9 twist is good.
If you go with an 8-inch barrel, you need to tighten up to 1:8.
If you go down to a 7-inch barrel, you better make sure it's a 1:7 twist.

Which is not how it works.

It’s certainly possible I misunderstood and I can’t find my original source. I was at least led to believe that the bullet needs a minimum of one revolution before leaving the bbl. Is that not the case? Why did Sig use a 1:5 twist on their 5.5” bbl? And most 8” bbls for 300BLK have a 1:7 twist.

[OlongJohnson]

Unfortunately, Sig doesn't consult with me on its design and manufacturing decisions, so I can at best speculate in a slightly educated manner. If I had to guess (and I do, if I am to answer your question at all), I'd say something like the shorter barrel is going to give up even more velocity, so they spin the bullet a little faster to keep the heavies that people will inevitably want to shoot out of it stable.

There's a page in this PDF from AAC that suggests very minimal increase in pressure with 1:5 vs. 1:7 twist, so that can be set aside as a concern.

https://ndiastorage.blob.core.usgovcloudapi.net/ndia/2012/armaments/Wednesday13590Silvers.pdf

The rotational velocity of the bullet is:

rpm = ft/sec * 60 sec/min * 12 in/ft * 1/#in

with # representing the inches of the twist, i.e., for 1:7 twist, # = 7.

I wouldn't necessarily rely on Courtney as a simple authority for testimony, but he has a discussion in this paper of several stability factors that have been used successfully:

https://arxiv.org/ftp/arxiv/papers/1410/1410.5340.pdf

On p. 2, he presents the Miller formula. It's clear by simple examination that an L^3 (length of bullet cubed) factor appears in the denominator, so it quickly becomes a dominant factor. Which explains why shooting long, skinny, heavies at subsonic speed requires a really fast short twist.

The key elements are how fast is it rotating relative to its velocity, mass, geometric factors and atmospheric conditions.

Note that the length of the barrel is entirely absent from the formula.

The twist rates that are popular in .300 BLK barrels are driven totally by the 220gr and heavier match bullets being fired at subsonic velocity. Long, skinny bullets at very low speed require extreme twist rate to get the rotational velocity up to stabilize them. If everybody stuck to 125gr and lighter supersonic, it's likely that 1:10, maybe even 1:12 would work just fine. I believe there is an extensive history of .308 shooters running 1:12, maybe even longer twist with 155gr bullets at long range (much greater velocity causing the bullet's rotational velocity to be correspondingly higher for a given length of twist).

I initially mentioned pistol barrels of 2-5 inches length with 16-20 inch twist rates simply to provide an example of barrels that readily stabilize their projectiles without the projectile coming close to completing a rotation while still in the barrel. Off the top of my head, I think there are even a lot of Marlin 1894s with ~38-inch twist. They're OK for 240gr .44 Magnums, even when the barrels are only 18-20 inches long.

There are other factors that come into play with other scenarios. In .224 caliber, lightly-constructed varmint bullets fired at very high speeds from a fast-twist barrel created to stabilize heavies can actually disintegrate in the air, just from the centrifugal force as they are driven well past 200,000 rpm. The prairie dogs will laugh and flip you the bird until you go get a different rifle. There's an issue with extreme long range that an overstabilized bullet may hang onto its original nose-up orientation rather than tipping and aligning its long axis with the flight path, leading to reduced effective BC and other issues with external ballistics. These are examples of why we don't just run super-short twist in every gun.

Long-winded dipping of toe into pool to explain my point...

[Welder]

....I believe there is an extensive history of .308 shooters running 1:12, maybe even longer twist with 155gr bullets at long range (much greater velocity causing the bullet's rotational velocity to be correspondingly higher for a given length of twist)....

Before bed every night, I read back issues of "Precision Shooting" magazine. Last night there was an article from July '98 about Palma rifles, and the author was saying his was running 1 turn in 13.5", shooting Berger 155 VLD's. Another recent evening an article in the same year range was mentioning 1 in 14" for his Palma rifle.

ETA we're talking .308 cal here.

[echo5charlie]

So what I found out was this upper was available separately or on AAC's MPW rifle that they made years ago when they were making rifles. Found some links to articles on that rifle:

https://www.personaldefenseworld.com/2015/12/the-aac-mpw-rifle-silent-knockdown-power/

https://www.gunsamerica.com/digest/suppressor-company-offers-ar-aac-mpw-300-blk-full-review/

The MPW was made in 9, 12.5, and 16" barrel lengths.

Here's an old ad for the upper by itself with a picture (obviously out of stock at this point):

https://www.cheaperthandirt.com/advanced-armament-corp-mpw-complete-upper-assembly-.300-aac-blackout-9-barrel-carbine-length-gas-kac-urx-rail-black-100884/FC-847128006848.html

The specifics I can find are the following:

-KAC URX III 8.0 forend, P/N 30210
-9" 1-7 twist nitrided 4150 barrel
-5/8"-24 muzzle with 51-tooth 3-prong flash suppressor
-Nickel-Boron UCT EXO BCG
-Bolt is Carpenter 158 phosphated / shot-peened w/ green o-ring
-Standard charging handle, forward assist, upper has T-marks and is lettered "300 AAC BLACKOUT (7.62x35mm) ADVANCED ARMAMENT CORP."
-The rail has the standard KAC markings and name, and is also marked AAC with the AAC logo on the forward right side of the upper quad section

Your opinions welcome. I'm ambivalent about the .300....might be fun, and here's a way to shoot it...but is it worth more selling? There aren't any current or completed listings for AAC MPW's with the 9" barrel; there are some for the 12.5 and 16's but unsure what the value on those is relative to the 9.

I have one of the 16" MPWs. It's a hell of a rifle! I have shot it to 750 yards on several occasions - not for serious as that is far beyond the ballistic realistic of the .300 - at 1 gallon paint cans in a stripping pit. Never got a direct hit, but made more than a few tumble down the bank, the hold over using the .300 BLK Trijicon 3x30 ACOG was simply silly and combined with unreadable wind it was a fool's errand but still fun. With subs at that distance it was impossible to even spot impacts into the silt bank.

I want to say that we were blowing these out (the 16", had over 100 of them) for around $1100 back in 2014/2015. Anyway, I regret not buying into a 9" MPW upper (or complete SBR) back then.

Anyway, to answer your question, there is no way I would ever sell my MPW. Ever.

[RevolverRob]

OJ’s point about stabilizing sub-sonics being a design parameter for Sig is correct.

Remember the Rattler is a commercial offering, but was designed at the request of a UK MIL unit among the design parameters were accuracy standards for both sub-sonics and supersonic ammo. Since the 110 Barnes stabilizes okay from a faster twist short barrel, stabilizing a 220-grain SMK was likely Sig’s main focus.

Also, the Rattler was meant to only really shoot subs when suppressed. I have no idea what adding a suppressor does (if anything) to the flight dynamics of a bullet. I know it’s possible that by adding tube length to the gun you can increase velocity by a marginal amount. It could be that given the fast twist rate and that adding a can to a Rattler can almost double the tube length - that a velocity gain from the can + twist rate stabilizes the sub-sonic rounds nicely, while have no real effect on supersonic ammo.

[Robinson]

...there is no way I would ever sell my MPW. Ever.

I also owned a 16" MPW and it was a very solid rifle. But with my Omega attached is was really heavy, and I regretted not buying one in a shorter barrel length for use with the suppressor.

Pshaw! I run a AAC 762-SDN-6 on mine. Now THAT adds weight. Sadly the SDN weight is great enough that it *slightly* disrupts the rifle balance.

FWIW to all, the 16" MPW weighs in at 7.3lbs unloaded and the SDN can at 1.25lbs...or just under M16A2 weight (8.6 vs 8.8).

This thread has me now looking for a NOS or lightly used 9" MPW upper......le sigh

Yeah, when I say "heavy" I don't mean too heavy to lift or carry -- I mean there was just a lot of weight out there toward the muzzle on the 16" gun with the suppressor mounted, especially with the hand guard the MPW uses.

So... Time to jack this thread a little.

Either they got a new production lot in, or some distributor found a pallet of CVA Scout V2 pistols in .300 BLK in the back of their warehouse. Hasn't been available for quite awhile, but they hit GB and a few other online spots this morning.

It's basically a big Spanish-made Contender. Same trigger guard release. 11.5-in threaded barrel. Decent trigger, supposed to be accurate. About $335 shipped and transferred, which is a heck of a lot less than a custom Contender barrel, and it comes with the furniture. Would be potentially very useful as an outdoors truck/tractor/campsite gun for targets of opportunity, plinking, handgun hunting whitetails and hogs, walking around chasing jacks, etc. type use cases. It should be maximally quiet, compact and beater-affordable with the cartridge.

Just to note, the butt stock for the Scout rifle will not go on the pistol receivers. Scouts are said to not be barrel-swappable like Contenders.

For context, the rifle version comes in a takedown that becomes two pieces ~17-in. long, so it easily fits in a backpack. The pistol version can be pulled out of the same backpack with a can on it ready to get a sight picture. Which allows room for the "get both" argument. Seems like a no-brainer to add it to the pile if one is going all-in on .300 BLK.

Thoughts?

How reliable is the expansion for the Hornady at lower velocities?

That's the thing about the Barnes - it has a lower threshold of 1300fps - And when shooting them out of a Rattler, most loads are in the 1800-2000fps at the muzzle.

[Norville]

The GMX shows Out of Stock at Brownells. I snagged 10 boxes back in April even before I had a gun to shoot it from.

Doc GKR recommends it, but not sure of what barrel length he tested or what the expansion threshold is.

I posted a thread in Ammunition looking for feedback on the Lehigh CCCu 115, but no responses.

The internets says 110 Barnes Tac TX is the answer, and apparently you can sell 70 plus cases in less than a day...

Let's be real, most of us in this thread are talking PDW distances, I doubt we'd ever need a shot past 50 yards, stealing the ballistic data off Hornady's website and a starting velocity of 1800 fps, you're good to go.

Range Velocity Energy
0 1800 791.0
100 1578 608.0
200 1382 466.0
300 1219 363.0
400 1098 294.0
500 1013 251.0

Edit:

Reading a bit more it looks like they need 2000 fps to expand for the 150 gr. Not sure if there is data for the 110s, I'll keep looking!

[entropy]

Not to be a....well....an “appendage”, but let’s just step back here a bit huh? Using the data listed in the above post (which seems legit compared to my own data which shows 1300fps@ 350yds out of an 8” barrel) how are you going to articulate that 200yd+ defensive shot?

“Looking at him through my spotting scope on 10x, he appeared to be a threat.”

If we’re talking four legged critters, different story, although even at 200yds, I’d be inclined to give whatever creature it was a wide berth and continue on my way. Except coyotes. I’d still shoot them...

I'm not worried about the 200y threat.

I'm thinking about the 0-75y threat, but firing bullets out of a 5.5" Rattler. I want to make sure I can get my penetration and expansion, when I'm starting below the 2000fps threshold that a lot of rifle bullets need to meet in order to properly expand.

The Barnes can be launched at as low as 1300fps from the muzzle and still expand and penetrate, which means when it comes out of a Rattler at ~1900'ish it will be fine for pretty much any conceivable distance.

I don't know what the GMX needs velocity wise to properly expand and penetrate. I would guess it's in the same vein as the Barnes, given the similarity in construction and purpose.

150-grain GMX .308s won't get pushed fast enough from a Rattler to expand. You'll still get penetration, but you can have both, at least with the Barnes bullet. In fact, a lot of the .308" bullets are marginal in longer-barreled .300BO (i.e., 11"+ where you get maximum velocity) for initiating expansion. I'm seeing a lot of guys over on 300BLKTalk are running the 150-grain Gold Dot, they seem to think it will perform as well in .300BO as it does in .308. I actually doubt that very much, even if Speer is loading that as a factory .300BO round, they have it tailored for longer-barreled patrol-oriented guns, as opposed to shorter guns.

I just copy pasted from the website. The point was that at 100 yards you're over 1500 fps. The last question is what velocity do the GMX rounds expand at? And as I said earlier in my post no one needs a shot over 50 for this specific purpose.

Let's keep what we're talking about straight.

The Barnes TAC-TX expansion threshold is more like 1300-1350 at impact, not the muzzle, and the expansion can be pretty minimal (just the tip) at those speeds.

I would expect the GMX to be more like the Barnes TSX and TTSX, which want to be in the range of 1800 or faster to initiate expansion. If you get down to 1500-1600 FPS at impact, they likely might as well be FMJ or solids.

Fair.

I was thinking more like, "If I launch this thing at 1300fps at the muzzle and hit something across the room - I'll get some expansion." Basically meaning no real velocity loss.

And yea...maybe just the tip.

Tac-TX seems to have kind of a sweet spot where you can get full expansion and penetration with an impact velocity as low as 1500 fps. When you throw it out of a Rattler at close to 2000fps, you'll be well within the sweet spot inside of 100y.

That's why it's 'the one'. If the 110 GMX performs in a similar range as the Tac-TX - it would be awesome. If it doesn't...then you're back to one solution for the Rattler the Tac-TX.

If you're running an 8" gun, you can use Barnes, Hornady, maybe even the Gold Dot (though I'm still skeptical that the 150-grain GD will perform well at anything below 2000 fps)

[entropy]

From what I have heard, the GMX indeed needs a 1800-2000fps threshold for reliable expansion. Both the 110 and the 120gr Barnes black tips have worked well for me. A number of years back, I bought a bulk of both as pulldowns from American Reloading. The 120s were actually boat tails, and I had hoped I would be able to squeeze a bit more accuracy from them. I could not. I ended up using those as blasters while keeping the 110s for defensive loads.

Somewhere around here (I know I kept it) was a 110gr I just happened to recover from a softer clay/sand backstop. The recovered distance was about 150yds and the thing looked like a damn archery broad head. The petals had peeled back nearly perfectly with only a bit of curl back, and the damn thing looked like something out of a science fiction movie. I was pretty impressed.

Had I known better, I would have ordered every single one of those things they had in stock. Out of about 800, I had maybe only 30 or so that were damaged in the form of cracked tips. Even those I shot.

Actually, the Hornady 135-grain FTX might be kind of interesting. Though, I'm not sure that isn't just the same bullet from the .30-30 leverevolution round loaded in a .300BO case. Well...I guess not I just went and looked and Leverevolution is currently 140-grain and 160-grain varieties. Though, I could swear there was a 135 at some point. Hmm, apparently Hornady is saying expansion of the FTX can be initiated as low as 1550 - but apparently penetration suffers a lot. Still going to have kind of a tight window in the short guns.

[PearTree]

How reliable is the expansion for the Hornady at lower velocities?

That's the thing about the Barnes - it has a lower threshold of 1300fps - And when shooting them out of a Rattler, most loads are in the 1800-2000fps at the muzzle.

It was my understanding gmx expands down to 1800fps. Where did you find 1300fps expansion for the Barnes? Everything I have seen says 1500-1600. Barnes also clarified the FPS figures include partial expansion, which I find a little misleading. Maybe DocGKR can weigh in?
I don’t have a rattler so I have no clue what velocities 110 gmx would have out of it. All of the Hornady testing I have seen goes as low as an 8 inch 1/7 barrel.

[ranger]

I wonder if the various 110 grain Varmint projectiles will be effective at 300 BO speeds from short barrel. They shoot great and very accurately out of my PSA 7.5 inch upper. Since Barnes etc. are sold out, I loaded up the 110 varmints. They may not go the FBI depth but I bet they make a large hole at the depth they do go

You know, it's just a number I've seen on the interwebs. So, I fired off an email to Barnes with the follow questions regarding the 110-grain Tac-TX in .308" diameter:

1) What is the velocity performance envelope for the Tac-TX in this diameter?

2) Is the lower number (minimum) enough to induce full or partial expansion?

3) Is the lower number (minimum) enough to provide substantial penetration? (I.e., greater than 12” in ordnance gelatin).

I'll report back what they tell me.

I’m canless, but running an ACSS reticle. I zeroed for supers, then just use the reticle for the sub holdovers. Pretty meaningless for me however. One day....

Got a notice from Wilson Combat that their .300BLK loading with the 110 Barnes TAC-TX bullet is back in stock. $36.95/box of 20. That would perhaps appear to fall into the "for sale", as opposed to the "on sale", category.

I guess I didn't know Costa was still around. I came across this video more or less on accident. It looks like he lives in Wyoming and is offering classes based at a dude ranch of sorts. Not unlike Buck Doyle in this regard.

Leupold had the dual reticle offering for awhile that had a central aiming point and then holdover lines for both subs and supers. EOTECH had something pretty similar for awhile. Maybe they still do.

Other optics like the SIG Romeo 4T with its reticle with 4 dots will likely work. It would just be a matter or shooting a few groups at 100 and 200 yards to see which dots best aline with which load at X distance. Nothing will be perfect since the two loads are so dissimilar.

I've had an AAC 9" PDW complete upper for years. I know almost nothing about it, except it's brand new. I remember looking on GB several years back and they were going for stupid $$, like $1200 stupid. More recently I haven't seen one for sale at all. Is this something worth putting to use, or is there something about it that makes it collectible?


When I bought mine in 2012/13, I remember the reviews being quite favorable. It had a reputation being able to reliably cycle all supers and subs, and at the time, I couldn't find another upper that came with such a good reputation.

My 9" upper has a URX 3, P/N 30210. 8" long.

I have an early 16" upper with a URX 2, P/N 20549, and it's only 10.5" long. A full quad-rail that's kinda cool with the integrated front BUIS.

Then a late 16" MPW with a URX 3.1, P/N 30326, and it's 13.5" long.

3.1 only has Picatinny at the front and rear of the rail (on sides and bottom), which makes it close in diameter to some of the new skinny rails. It did lose the integrated front sight. It’s my favorite KAC rail, and one of the reasons I originally bought the AAC. Although, now it plays second fiddle to an SR30.

With regards to the AAC MPW rifle, a week or two ago I PM'd an ex-AAC employee on another firearms forum asking for the history of the rifles and why they were discontinued. I got that response today and it sounds like a couple MPW fans here might be interested. Here it is, with names redacted:




I was part of AAC from 1998 until early 2019. The MPW's were and are wonderful products. A lot of thought went into the whole system. The idea was to have a turn key 300 BLK AR (somewhat rare back when the MPW's were introduced). The idea was to combine Mil-Spec uppers and lowers with a nitrided 300 BLK barrel and tuned gas system with a host of the best commercial off the shelf AR parts. The bolt carrier was very special at the time. The nickel-boron finish was revolutionary for the time, as was the reduced diameter section to minimize drag in the receiver. The cam path on those bolts was special too. The cam path was curved to provide a smoother unlocking motion. The lowers were nothing special. Most of the parts were off the shelf Bushmaster or DPMS parts, with a nice Geissele two stage trigger.

If you have a chance to get a stripped MPW marked lower, make sure you can return it if the pins don't line up with the upper. There were some lowers that got made that have very tight fits with the pins.

This is going to sound odd, but the real reason the MPW's were dropped was jealousy and competition with DPMS and Bushmaster. The MPW's were hands down the nicest, and most advanced AR's ever made by any of the Freedom Group companies. This sparked immediate jealousy and outrage from DPMS and Bushmaster, who lobbied non-stop to have the MPW's dropped so that AAC could concentrate only on silencer development. By the time Remington Defense got in on the act and introduced their own AR line, you had four entities in the Remington/Freedom Group family all making AR's. Despite the fact the MPW was far and away the nicest, most content and feature-rich AR's being made by Remington/Freedom group, it became an easy choice at the top to axe them from production.

I bet they wish they had a warehouse full of MPW's right as Covid hit. They could have sold every one of them for full retail.

Let me know if you ever have any questions about anything AAC or silencer related.

[spelingmastir]

I saw that on another site too....but my 8" URX 3 doesn't have an integrated front sight.

ETA probably because lack of space for one. But that explains my confusion because otherwise I'm not seeing a lot of difference in the two versions.

Found some for $.34/round!

Well, sort of. Ordered a case (20x10) from a well-known supplier. A few days later, a big box arrived on the front porch. Scratched my head, opened the box, and there were four boxes inside. Math not being my strong suit, three times I multiplied 20x10x4. Got 800 every time. E-mailed receipt and enclosed invoice were both for one case. Checked credit card on-line; one case cost charged. This was on a Friday. Sent supplier an email explaining.

No response by noon on Monday, so called Customer Service. Told nice lady I was undercharged, and explained. She said something like "You . . . you . . . you ordered one, and got four? And you're calling to tell us?" Uh, yes. "Did you want to return the other three?" Well, no, I'd rather keep them, but figure I ought to pay you. "That's . . . that's . . . that's so nice of you. So nice. Can I offer you $20/case discount, and not charge you state tax?" Uh, sure. That'd be great.

A win-win!

2) Is the lower number (minimum) enough to induce full or partial expansion?

3) Is the lower number (minimum) enough to provide substantial penetration? (I.e., greater than 12” in ordnance gelatin).

I'll report back what they tell me.

Received a detailed response from Barnes this afternoon:


The minimum IMPACT velocity required for reliable expansion and penetration on these 30 caliber bullets is as follows-
For the-

#30321 110 gr TAC-TX (with the large black colored tip designed for the 300 Blackout) needs 1350 fps.
#30320 120 gr TAC-TX (with the large black colored tip designed for the 300 Blackout) needs 1350 fps.

#30358 110 gr TAC-TX (with blue tip designed for 308 Win velocities and higher) needs 2000 fps.
#30362 110 gr TTSX (with blue tip designed for 308 Win velocities and higher) needs 2000 fps.
FYI- #30358 and #30362 are the same bullet just put into a different box.

#30336 110 gr TAC-X need a minimum of 1900 fps.
#30341 110 gr TSX need a minimum of 1900 fps.
FYI #30336 and #30341 are the bullet just put into a different box.

#30364 130 gr TTSX needs a minimum of 1800 fps.

And some additional information was also provided:


If using in a 300 Blackout I HIGHLY recommend the 110 gr TAC-TX black tipped bullet SKU #30321 as well as the 120 gr TAC-TX #30320. They are designed for the 300 Blackout and to expand at those velocities (down to 1350 fps).

The 110 gr TTSX or 110 gr TAC-TX with the blue polymer tip #30358 and #30362 are designed for 308 Win or 30-06 COAL’s and velocities . It requires 2000 fps to reliably expand (small expansion). More full expansion it needs 2200 fps or more. In a 300 Blackout from a tree stand you may get some expansion with the blue tipped TTSX but the hydrostatic shock/wound cavity will be much smaller than the 110 gr (black tip) for the 300 Blackout.

So for a 300 Blackout you definitely want the TAC-TX with the large black colored polymer tip in 110 gr #30321 or the 120 gr #30320. Due to the high weight retention and penetration depth I recommend usually the 110 gr over the 120 gr for a higher velocity and a slightly better wound cavity for most game and situations.

If for a 308 Win or 30-06 type cartridge then you would be better off using the blue tipped TTSX/TAC-TX.

Same with the 130 gr TTSX. It is designed for a 308 Win or faster velocities. It needs a minimum IMPACT velocity of 1800 fps for reliable expansion.

Finally:


At the minimum velocity of 1350 fps on the blackout 110 gr bullet it will still have large expansion.

Directly from a Barnes Ballistic Lab Technician (I've withheld his name because this a public forum).

Translation -> Barnes Black Tip Tac-TX is the shit - reliable expansion down to an impact velocity of 1350fps -> 110 is slightly better than 120, but 120 will do the job. Buy whichever one you can find.

I'm just old-fashioned I guess, but I like the GI 20-rd aluminum mags. Mine all even have the original metal followers still. Am I going to run into any feeding problems with these and 300 BLK? From supersonic to subs, interested in the whole range.

I'll buy BLK-specific polymer mags if I need to, I just don't want to if I don't have to.

For supers the OALs and bullet shapes are generally close enough to 5.56 shapes you shouldn't have an issue.

For subs you may need a .300BLK-specific magazine. You'll have to try it and see. With poly mags, it's the front rib that contacts the bullet. With a 20-round metal GI you may not need the extra clearance.

Then I’d stick with the A2 hider. Spend money on a device later when you shop cans. Muzzle devices can be crazy expensive and they evolve. The newer designs today keep the threads from getting caked with carbon so removal is easier. And some cans like the Trash Panda come with muzzle devices.

I was able to source it locally in the past for fairly low cost. I stopped purchasing it after the 3rd blown primer and flipped primer in 2 boxes with the same lot numbers. This was over 2 years ago and i do not recall the head stamps on the cases. I want to say they were Hornady head stamps because I threw out all of my 300blk Hornady brass I was saving for reloading right after this @ 600 count. The Barnes loading was the only 300blk super I was able to source at that time. Had tons of UMC 220gr available but I needed supers for a pig hunt.

so I will be in business on a carbine upper to go with my Ruger Ranch and PSA pistol upper, part of my motivation for getting mo bullets last night.

If nothing else it sure is a pretty black finish.

MidSouth has some Barnes 110 projectiles in stock so I got 150 and loaded them up with H110. Prefer factory but I guess my reloads will have to do for the 300 BO PDW.

Inspect that Faxon very, very carefully. I've had a few in my hands. I found that the best price I could come up with on a Wilson Combat and a Criterion made the higher-quality barrels a no-brainer compared to the best price I could come up with for the Faxon.

Example (https://www.opticsplanet.com/wilson-combat-ar-threaded-barrel.html?_iv_caliber-193146313=dot-300-aac-blackout&_iv_code=C0-ATB-ARTHBRL-TR-300RAPG16RT7)

Note that you get 10 percent back on credit toward future orders (at least as a logged-in customer, at this time), and Optics Planet frequently has discount codes for another 10-15% off the top, or roughly equivalent flat amounts such as $15 off a $150 order.

In the cases of the barrels I ordered when I ordered them, I did have to wait a little while for them to come in stock, but not as long as I've been waiting for Faxon to make more so they can send me the second replacement for a defective part, after the first replacement was also defective.

I remember now you posting about an issue, what was the thread so I can review?

It turned out the replacement barrel they sent had issues as well, which were not as obvious, but when I started checking more closely before assembly, became clear. Sent them some pics and they agreed that it is not right and offered to replace it, but they apparently have not run that SKU again, as I am still waiting for the replacement barrel.

Before discovering the issues with that barrel, I picked up another Faxon barrel, a 7.5-inch .300 BLK. It seems to be usable, except that my preferred muzzle device won't clear my preferred handguard with a 7.5. (I apparently made some bad assumptions about lengths of various handguards when making measurements before ordering.) That's why I bought a WC 8-inch barrel. It's way nicer, and was only about $70 more.

Midway just got in some Barnes 110's for those interested.

At least it's available. And not unlike most other popular calibers, a significant price increase over the summer. About three months ago, I bought the same .300BLK loading for $26.99, so the above price is a 48% increase.

But there’s a $3 a box rebate, so maybe only a 40% increase. Painful nonetheless.

Typical for me - - - I missed the rebate notice.

While I don't have what I'd consider a plentiful supply of 300BLK (actually, not sure what I consider that to be, compared to, say, a high-volume-shooting round like 9mm), one of the local ranges does manage to keep some range-quality 300BLK. Limits purchases to 2, 20-rd boxes, usually for about $.70/rd +/-, so not too bad. Several local shops are limiting the majority of their ammo sales to those buying a gun.

Somebody greased the damn slope and left a banana peel at the top for me to step on.

I'm building a PDW. Was going to go .223 since I just built my first AR and ramped up to load .223. But then I looked at the reloading data for the .300 and said hot damn.

Luckily I had an Aero lower laying around and managed to pick up a matching Aero upper & BCG, YHM 7.5" quad rail, 7.5" Faxon bbl (from a forum member, no less). The brace & other goodies are en-route.


No I just have to figure out a sight & ammo logistics.

7.5" Faxon bbl
I have a 7.5" PSA upper and bought the twin in 223, and 7.5" is a good reason to have 300BO!

I was just able to order fifteen boxes of Barnes VOR-TX 110-grain, from Cabela’s main site. Good luck, y’all.

Midway USA sent me an in-stock notice For this same load, a few days ago, but I was unable to react soon enough.

I just received an in-stock notice from Midway USA, at 0703 HRS, 07 October, regarding 300 BLK 100-grain Barnes VOR-TX.

Good luck, y’all!

(I reckoned that it might not be polite to post a direct link, as Midway USA purchases do not provide affiliate-link financial benefit to P-F.)

Edited to add: it is good to finally be able to vet enough carry mags with a specific, favored defensive load. I had originally been concentrating on buying 125-grain loads, but their availability, across several brands, severely diminished. Barnes 110-grain VOR-TX has been popping-up, several places, recently, so I have shifted attention to it.

Quick Q: favorite place to buy either the lancers or gen3 .300 pmag? TIA.
