I picked up a nice M1812 made in 1816 and there is a ball in the bore. I used a snapon snake camera and it sure looks like the flower of a paper cartridge. I know I could just get a ball puller, but does anyone have an idea of how to get it out without destroying it given that it is a relatively loose fit? I understand it is a long shot that it could be an original cartridge but part of me wants to see what comes out in an undamaged state. Also is it dangerous to life and limb or the firearm to leave it since I don't wish to fire it?
