In my #2 Ballard with 28 inch lined barrel and the H&G #65 bullet (98 grains lubed) and CCI SP primers. 5 shots through my Chrony. These loads were some that I found in old manuals or were given to me by folks on the list or some I just figured would work. Listed by Powder, Load, average FPS, ES and SD. Yeah, I know ES and SD don't mean a lot for 5 shots but you'll get the idea. More comments at the end. Here goes:
Titegroup, 2.0, 904, 110, 42;  231, 2.6, 646, 147, 80;  AA5, 2.7, 690, 98, 40;  AA5, 3.0, 610, 72, 29;  AA5, 3.3, 709, 24, 11;  Bullseye, 2.3, 1345, 19, 9;  2400, 5.6, 744, 37, 15;  Unique, 2.4, 868, 116, 53;  Unique, 2.6, 1002, 46, 20;  Unique, 2.8, 1012, 70, 32.
Best looking groups were AA5, 2.7 (in spite of the higher ES and SD than the 2.9?) and 2400, 5.6. Bullseye really zipped out there and had low ES and SD but scattered the shots. I'll try less there. The H&G #65 is a good pistol bullet but I have other bullets I will be trying next (as soon as I cast them). I don't think that 110 or even 115 grain bullets will be a problem. I had thought that some of the other loads would be traveling quite a bit faster than the pistol level loads out of a rifle but that is why I'm testing. Only the Bullseye load went supersonic and that with no indication of any problems. I can't explain the numbers for AA5 2.7 vs 3.0 - it sure looks like they should be swapped. We'll see. Ding! End of round 1.

Yes, interested in your results. Being an old bullseye pistol shooter, with hundreds of rounds of brass, dies etc. in 32 S&W Long I have many times thought about chambering a rifle in that cartridge.

I'm interested also. I've got two rifles in 32 S&W Long. I've only shot Unique powder in them. My favorite load is 3.0 gr Unique with a 100 grain bullet from Accurate.

Closing in on some accurate loads. Was out today with 3 bullets and 2 powders and 3 loads for each combination. Will modify this post when I get through the analysis. Sure like that DST. So it was like this, I was planning to go to the range early Wednesday so I had time to get organized for that. Turns out wife informs me I was on Uber duty for her on Wednesday so I threw stuff together on Tuesday and got a late start. My usual procedure is to cover the whole target frame with paper and attach 9 aiming points to it. Since I had 18 loads that would require two covered frames and 18 aiming points. I had cut out 3x3 dark paper squares for my aiming points. I got to the range and found that I had rushed out without putting the paper roll in the car. OK, I'll just have to use 18 targets. Uh, didn't bring the big box that had the targets in it (since I wasn't going to use them). Fished around in the target shed and found 2 target frames that had no holes in them. They had a dark backing so my 3x3 squares would show up. Starting setting up the bench and remembered that the big box with the targets that I didn't bring also had my rests and bench cover. Grrrrr. Got a rug from the sandbag box and found a front rest that someone had left in the target shed. Finally. the 3 bullets I had were the Lee, 99.8 grain that cast .312; a Saeco 322, 98.4 grain that cast .312+, and a Lyman 311159, 117 grain GC that cast .313 (why this one? I had a lot of them for some reason and I wanted to try a heavier bullet). The Saeco is very similar to the Lee in appearance but nicer looking with a wider base band. Unfortunately, looks not being everything it didn't do well in the testing. They were lubed in a .313 die. The powders were AA5 and 2400. The loads were in the vicinity of the ones that looked like they might have promise in the initial test. For the AA5 there was just a slight 1/4 grain variance among the 3 loads and for the 2400 more like increases of 1/2 grain as I wanted to get up closer to the 6.5 grains that had been mentioned to me. I was shooting at 50 yards as I had a nice crosswind. The Lee was happiest with the heaviest load with each powder with 1 1/2 inch groups. The Saeco flunked the AA5 test but seemed to like the heaviest 2400 load with 4 of 5 in 5/8 inch and 5 in under 2. The surprise was the Lyman which was closing up with each increase and was down to 1 5/8 with the 2400 and is going to get increases in powder next time.

That would be a nice one to have, Mal. The only pistol I ever had in the cartridge was a K32 but I never played with it enough to get satisfaction. Loads that light seem to be a problem for me. Were you using a rotor or actually weighing them? I got a kick in the head today when I was trying to nail down the actual powder weights I was using from the settings on my Harrell's Schuetzen for the AA5. Even my 10 drop averages weren't coming close. It just doesn't like loads of AA5 around 3 grains. I would have to weigh them one by one to get a consistent load in that range.

I regret to this day trading off both of the low walls that I had converted from 32 rf to cf. one was still in 32 LR (32 Colt) chambering and the other had the chamber recut to 32 H&R.   
In my dotage, I’m hoping to make up for their loss by having a Ruger #3 rebarreled to 327 Fed Mag.
