Thanks guys. I really was asking about buying already cast bullets but your mould suggestions got me thinking on a couple of levels.
The only casting I do is round ball for my BP rifles so my Production Pot is available. I also have a (limited) supply of wheelweights. A little casting might be fun, as long as I can shoot them as cast and the lube is easy to apply.
But y'all made me realise that I need to slug my barrel and decide on what to do about the cylinder throats. Seem they are a little tight as I remember.
Oh well, guess I'll think on it while I burn up some powder using up what's left of my box of Hornady swagged 240 gr. swc's. Which, BTW, pattern worse at 25 yds then a load of 00 buck does at 50!
