For both my 7 1/2" Bisley SBH and my 5" RH I shoot Sierra 240hp, 240sp, 250fpg and 300gn SP with great accuracy from 296, 2400 and my favorite AA#9 powders. AA#9 is cleaner, meters better than anything, and you can load it to the hilt. Kesselring has AA#9 on the shelf. I shoot hard cast lead pushed by 2400 for plinking (An Elmer Keith load), and only use the jacketed spendy stuff for hunting. Even if you hit a rib or two, at 15yds, a hot loaded 300gnSP Sierra will go through a good sized blackbear. Two blood drains!
