Pearce is always a good place to start for revolver information. I'm especially curious about muzzle blast.

Thanks. I’ve been planning on researching appropriate powders, especially since one of the local shops said to expect significant price increases on powders soon. I have Unique and 231 on hand, so I’ll probably start with those
I had the opportunity to chrono some factory 32 S&W Long from a 4 inch I-Frame.
32 S&W Long Magtech 98 LWC Ave: 719 fps 6 shots
32 S&W Long Sellier & Bellot 100 grain LWC Ave: 674 fps 6 shots
This is 32 Long, not 32 H&R Mag. The 12 shots went into a 6 inch group on a steel target at 25 yards. Standing, off hand and I could almost see the sights on that ancient revolver.
This is recent ammo ordered online.
A few years old now. I don't know which loads are / are not in production.

Currently have some @Lost River WC inbound, some Starline brass and RCBS dies that I horse traded for.
One minor observation. Starline does have 32 H&R brass in stock right now but it's likely to dwindle quickly once the pistols start getting into people hands. some of you might want to get some brass stockpiled.
Just a suggestion.
I’ve been looking around online for data to load 98 - 100 gr hard cast wadcutters in .32 H&R but have had no success. I’ve seen a little for HBWC but I would like to drive them around 750 fps out of a 2” as a training analog.
Have any of you run across anything?
Hodgdon has several loadings as high as 100 grs over 6 or 7 different powders

Seems like a good starting point… maybe?
@Outpost75,
Opinions on the above?
No.pressure data.
No.accuracy data.
Not enough info.on test conditions.
A puff piece to sell powder.

I did a Google search for 32 H&R magnum reload load data and found a lot of results.
I just ordered a copy of the Lyman Pistol & Revolver Handbook 3rd Edition Reloading Manual. I am told it has the answers we seek. I’ll let you all know when it comes in.
The manual came in. It only has data for a 90 gr swaged HBWC and a bunch of jacketed bullets. Lists starting loads with a number of different powders so that is helpful. Not exactly what I was hoping for but it helps.

I haven't been following this thread since I'm planning on getting one of the .38s.
That said, don't use data for RNs/SWCs to load WCs. Wadcutters are seated much more deeply and using the other data will raise pressures a bunch. I'd use the HBWC data and go from there.
@4given
Compared to my 47th edition, published in '95, the current manual omits a 72gr (#311252). All other data is completely unchanged.

I just set up my 550 for 32 S&W Long. Since the reason I'm going to the 432/632 is for less recoil, I will be mostly shooting 32 Long in it.
I'm loading a coated 100 grain SWC over a starting load of Bullseye. I've only fired a few rounds to test. Looks like it goes about 680 fps in an old I-Frame.
During my research, I wandered over to the Bullseye Forum where they're shooting 32 S&W Long out of Bullseye guns and getting astounding groups at 50 yards.
I'll probably got some of @Lost River's wadcutters for carry.

I haven't bought one of the new UC guns (yet!), but I have three 32 revolvers, the 2" LCR in 327, an older 432, and a 3" 327 TORO from Taurus. I worked some loads up and did some chrono, gel, and accuracy testing with all three guns with 32 long, 32 H&R, and (for the LCR and Taurus) 327 fed mag loads. I didn't have my H110 with me at the time, so the 327 loads should not be considered "full power" as I was using titegroup. I used both 85 grain Hornady XTPs and a 100 grain flat point bullet that I stocked up on through american reloading years ago. I will need to compile the data, but I'll put it in here as soon as I have it.
Even though I have a number of other powders that are better know for revolver loads, I have actually found that Titegroup has been a great option in the 32 guns due to the relative small volume. When shooting jacketed bullets the smoke is a nono-issue. I will be working up loads for a coated wadcutter in the next couple of weeks and perhaps I'll have to re-consider my powder selection for those bullets, but for the 7-8k of the 100 grain jacketed bullets I'll likely use Titegroup for most of them.
Second small batch, pre seat / crimp.

Looks like Sunday will be range day.
For those with experience loading the .32 H&R Mag. would 231 be a better all around choice than Unique?
My SD is not where I would like it to be with Unique. If the easy button is going with 231, I can go that route.
@Outpost75 @Lost River
Did lots of testing with 231 when I was at Ruger. WAS the powder of choice!
Don't have the pressure-tested data but 3.5 grains was good full charge load with 85 XTP in .32 S&W Long brass and 4.5 grains in H&R Mag brass. As high as 5 grains in HRM was fine in the SP101 but substantially exceeded SAAMI MAP approaching 30kpsi IIRC.
231 would be a good choice.
Tightgroup, and Tightwad would both be ones that would be pretty easy to work with as well. Pretty easy to get moderate velocities with a variety of powders. The hardest part about working with the .32s is handling the tiny cases. As compared to larger cartridges like a .44/45 they are darn small and your hands cramp after doing it for long periods of time! This is true of any small calibers really. I was just on the phone with a bullet supplier last week and he mentioned the same thing when loading .17 caliber rifles into his 1050 Dillon by hand.
The fact that you both responded within 20 minutes is amazing. Love this forum.
Funny you mentioned that.
We were talking on the podcast with Jason from Lipsey's and I mentioned all the people who hang out on this forum. I didn't really get a chance to go into it, but it really could be a pretty good topic of conversation. This place is pretty (actually very) unique on the web, in the people we have hang out and contribute here. The extremely wide cross section of folks is such a cool thing and makes this place what it is. Outpost is a walking encyclopedia of knowledge, and guys like Bruce Cartwright are another source of serious info on all sorts of subjects. If you have a question on lever actions, we have guys like Malamute, and the list goes on.
There really is not a place like this out there, and it really is not just about guns, though that is certainly obviously the primary focus.
But does it matter??
I mentioned previously my displeasure in the velocity spread and SD. I did some shooting today at 25 yards. Using a different grip technique, more similar to an auto grip, I shot some acceptable groups.
More crush grip needed:

Not sure if it's worth chasing better SD for practice ammo.
