Comment: They'd love 'em!

Thirty rounds, one shot per trigger pull, and far more accurate than a musket? Yes, please!

Actually, Jefferson would probably geek out over them, seeing as he was a bit of a gun nut himself.

Also, as others have pointed out, they had CANNONS. That could be loaded with GRAPESHOT.

Think of a shotgun loaded with buckshot. Now increase the bore size five times over. Now multiply the number of pellets by twenty, and make them bigger.

Yeah. I don't think a Kalashnikov would horrify them.
