Anyone else use .22 shorts CB rounds? I had firing these for a while in my old roommates backyard. Now I'm married and renting a house, I built a nice (and safe/ventilated, no worries) backstop and have been firing them in my basement. Obviously there is no issue firing these out of a bolt or lever action, but is there a problem firing them out of a semi auto? Obviously, because of the primer only charge, I have to eject/chamber each round manually, I just want to know I'm not doing any damage to my firearms. 24/7
