I have some that I have never shot, they have been fired in the past. My Grandfather gave to me, and some of them probably should not be shot anymore. 1868 ish,black power 10 ga.shotgun, Old Remington 10A riot shotgun (told takes paper shells) 1880ish break open Scoldfeild (spelling) Revolver, 1943 P-38, Luger, WWII era Colt .45 1911. Except for that kind of stuff, everything else is for making holes.
