I can tell you've never shot black powder weapons before lol. As an owner of several each and everyone of those guns shoot will still very lethal accuracy. Also you haven't heard of a Remington 1858 before have you? Quick change cylinder and can fire six shots. Just as lethal as a semi auto.
"Imagine trying to shoot up a school." ?
What do you think thats what pro-grun advocates think about all day? For a lot of us shooting is a sport. Also snip your images you moron, they're stretching the thread. It was also pointed out in previous posts that the right to bear arms by a lot is considered just having people past or present armed in general, for protection against foreign invaders and also protection against our own government should they decide to go evil on our country. If you even had the attention span to notice that.
Also you forgot about the Minie-ball ammunition which appeared very soon after the revolution. Accuracy is no longer an issue with black powder weapons. I don't feel like i can credit you with having much knowledge about guns anyhow.
