Ive got a 58 cal air rifle made by Haley out of Mississippi. Its a monster of a gun, and kicks like a mule! People are killing Elk and Bison with these things! Now why should I call that a primitive rifle? There were air rifles out there before there were cap and ball rifles. Lois and Clark had one on there expadition when they went west. As a matter of fact, it may be the reason the natives allowed them to pass without a fight. It fired a 41 or 42 cal ball, and had 20 rounds in a tube mag which made reloading real easy. Alot more intimidating than a musket they had to reload in several steps.
