Lost River Ammunition

[Paul Blackburn]

It is no secret that poly-coated projectiles have become more and more popular over the years. In fact, the last few loads I have developed, I started with a poly-coated projectile right from the start. They smoke less when the gun is discharged, and make cleaning easier, plus you are handling lead a bit less if that is a concern. Accuracy tends to be excellent with them as well. Really there are no downsides.

I recently developed a good load that is suitable to replace the .38 Special standard pressure 148 grain hardcast wadcutter. So the new poly-coated 148 grain wadcutters will be offered from here out. They pair up nicely with the little .32 H&R wadcutters too!





Hope you guys enjoy them!

Have you done in penetration tests with these .32 and .38 wad cutters?

Just ordered the last 100 rounds of poly-coated .38.

Ammo: Lost River 44 Special 240 grain LSWC

Gun: Taurus Tracker with ported 4" barrel (closer to 3" as the final inch under the porting is counter-bored fairly wide)

Five shot string over a chronograph:
1) 877
2) 893
3) 893 (dup 1, not an error)
4) 907
5) 897
Ave.) 893.4 feet/second
Energy*) 425 ft-lb_f
Sectional Density**) 0.185

For comparison, the sectional density of a 158 grain .38/.357 bullet is 0.177 with a muzzle energy of 253.5 ft-lb_f for a representative warm standard pressure load clocking 850 feet/second.

Before the chronograph, I ran a Hayes 5^5 (five shots, five yards, 5" circle, in five seconds) and it was quite comparable to a Charter Bulldog firing a 44 Special cowboy load (240gr. at 660fps). Both were comfortable and passed easily.

A 25 yard group showed good promise but the gun was not zeroed for this load so no measurement taken as it wasn't all on paper. Some 15 yard shots at a head-sized rock pock-marked the surface notably more than lighter specials. I'd like to hit some targets of various material to get a feel for how the bullet holds up but would likely not hesitate to shoot a deer with this load.

Some more notes with the 44 Special load.

4" S&W model 329PD: Recoil is roughly comparable to shooting a S&W Shield in .40 with full power 180gr. service loads. Taking aim at a punky but soaked 6.5" diameter log, the bullet passed through the thickest bit and blew splinters out the back, where it was still truckin' enough to splatter wet earth. Hitting a few other targets of opportunity at various ranges out to fifty yards along my walk, I can now say that I would definitely feel comfy with this load for whitetail.

Charter Arms Bulldog with 2.5" barrel: While it passed the Hayes 5x5 with time to spare, WOOF. It's about like shooting a moderate 44 Magnum from an N-frame. I will not repeat the "experiment" a friend wanted done with his snub. Not painful but the snub squirmed around and it could not have been good for the gun. In just seven rounds fired, the revolver was filthy. The final two did stay within the 4" center of a 6" paper plate at 15 yards with a dead center hold for a cylinder of ball and dummy. I am an idiot on the internet and no one else should bother to do this. The Blazer aluminum cased 200gr. Gold Dot load I fired for comparison was already sportier than I felt would likely be good for the gun in the long term.

Just ordered the last 100 rounds of poly-coated .38.

I have a 1K plus rounds up on the website now. Forgot to update that here.

Also have a bunch of the ever popular 9mm+P Predator Penetrator!

Plus .45 250 grain +P and .40 S&W as well!

[Lost River]

New 9mm+P 148 grain Poly Coat Flat Point "Predator Penetrator", Velocity 1125 FPS

Velocity as tested:

Glock 17: 1125 FPS

Glock 19: 1118 FPS

CZ-75: 1126 FPS

Glock 34: 1156 FPS





This high velocity, deep penetrating load is oriented towards those who want to use their carry gun or home defense gun on the trail, or while hunting, for defense against predators.

WELL over 1K rounds fired through my tupperware and extremely reliable.

Not too long ago I ran some 6 shot drills with the 9mm 148 grain loads, and the .45 ACP 250 grain Poly loads

I was using a Glock 19 and a Glock 21 for the drills.

I was shooting at a 2/3rd size USPSA steel plate.

The results

With the heavy .45 250 grain +Ps in the G21:

.43 was the first shot.
1.56 was the last shot.

















So 1.13 seconds for 6 shots.

Bear in mind that I don't shoot competition anymore and I am not as fast as I used to be, and I didn't do any warm ups. But I figure that was good enough. This was also from the low ready not from a holster, BTW. I was just interested in seeing how the guns and ammo did and seeing a time comparison.

With the little Glock 19 using the 148 grain +P ammo:


.55 reaction time to first shot.
1.57 was the 6th shot.
So 1.02 seconds for 6 shots.



The gun ran perfectly.

I ran another six shot drill and got a 1.58.

That seems to be where I am at. in the 1.5s. If I want to get all my hits, it does not matter what cartridge, I need to be right in that "window".



So anyways, yep, the gun and ammo runs like a top.

I love it.
