My normal load is pretty much strickly for CAS, 70 grains of 2F black powder, a lubed fiber wad and overshot card and roll crimp with 1 1/8oz. #6 shot. I've been thinking of trying some buck shot loads, but with the price of shot now days I'm thinking of casting my own. I already cast for 36 round balls, what's the standard buck shot load sizes? Will a 31 cal mould do for 00? I figure I'll need the cylinder choke in and overshot card. I've been thinking of using the 36 round balls and filling the space with #6 shot and see what happens.
