I'm thinking that I would like to try a round or two of shot out of my half scale Napoleon if for no reason other than just for the fun of it. Really have no idea on just how to go about assembling a shot cartridge though. My current thought is to put it together somewhat like the foil wrapped powder cartridge but with only a couple layers of foil and a cardboard plug added to the bottom of the cartridge. My normal round ball weighs right at 2 1/2 pounds so I am thinking of using around 2 1/4 pounds of 36, 45 or 50 caliber round ball. Any of you have experience at this?
