I just picked up a Colt SAA 45 colt manufactured in 1892. The gun is in excellent mechanical condition, very tight, crisp clicks, solid cylinder lockup. I would like to shoot this old gun but don't want to damage it in any way. It is a black powder frame gun and does not have the smokeless proof stamps on it. Is there somewhere that manufactures ammo that would be safe to shoot in this gun? The gun is not going to be a frequent shooter but more of firing off a few rounds for the nostalgia of shooting a 118 year old gun. So I don't want to buy dies,brass, bullets, primers, powder, etc just to shoot it a couple of times unless that is my only option. Thanks!
