well, i'm kinda worried about steel shot. i remember when steel shotgun shells first came out. i heard so many scary things about them, that i still won't use them. most of mine are antiques anyway, but there are some still made today that are not recommended for steel shot. i know a shotgun is kinda different than a cannon, but if certain shotguns can't use steel shot, wouldn't that go for cannons too?i'm not trying to be smart or anything like that, it's just that, about all i do is shoot. honestly, it might take a month or two in my free time, but i can put 500 shots through a small cannon. what can i say, it's fun to go shooting ;D
