Personally, I've always used 125g jacketed SP's for my small game needs, but since I've recently started casting bullets, I'll be finding a suitable one for my plinking/small game loads.
I have been shooting a 95g SWC in my 32 magnum Single Six. I'm using Trail Boss with that load, and 2.4g fills the cases within about 1/10" of the bullet base, pushes that bullet at around 750 fps(muzzle), burns amazingly clean, and is super accurate with very small extreme spreads. When I get a mould for my Blackhawk, I'm planning on trying Trail Boss in it too. I've only heard very good things about this powder.
