I've had a tough time finding 'good' loads. All I use is lead bullets (for all calibers I shoot). For 78g RN I found 3.5g of AA#2 works well. Under 100g RN 5.5g True Blue. Under 115g RNFP, 5.0g of AA#5 (5.0g of True Blue is good too). YMMV of course, but this is what I am currently using for loads using these bullets to get acceptable accuracy. I found I have to go with powders that flow like water (really small granules) to get consistent powder dumps with these small powder weights for the little cartridge. Obviously that puts Unique on the 'do not use' list (I did try it) for me.
As I've said elsewhere, I call the .32 H&R my reloadable .22. I think it will be good for that when .22 becomes the unobtainium cartridge again down the road sometime. Good to have around.
For a guy who said he'd never own one (I own .22s and .357s... so why?) , I now have four of them... a Baby Vaquero, a .327 SS Single Six, a normal blued Single Six, and a Birds Head Lightning.... Go figure. Never say never I guess!
