I know "best" is subjective, so here goes... I've got a T/C Encore rifle with a 20" 500 S&W barrel on it right now. I've cast up some 440gr keith boolits from MiHecs 501-440 cramer mold. My solids are dropping right at 445 grains sized(.501) and lubed. I don't really want barnburners, but looking for a good solid hunting/plinking type load that doesn't abuse my shoulder after only a few rounds. I've got A1680, W296, Lil' gun, and RL7 on hand. What say you on the "best" powder, even if its not one of the ones I have. Thanks!!!!!!
