WOW. A 3500 grain roundball and a 7000 grain conical. Maybe the extra 3500 grain in the cannon of a musketis a bit too much. Perhaps the question to ask is, given the choice, would a General in the 19th centurywant his troops equipped with roundballs or miniballs. If I were a general in the 19th century (saya civil war general), I certainly know which I would choose.

Stay clear of any 1/2lb. roundballs, they are murderous things.

Happy hunting, Phil
