I walked through an antique store in Tappahannock Virginia a couple weeks ago and found a brass capper, one of the straight line type, sitting in a random box of tools. It's a bit tarnished, but not bad. I didn't need it, but just couldn't leave it there. Gave 'em 2 bucks for it. Thing is it had 8 or so old caps still in it. They look brass in color, and are cut uneven on the open ends. Now I've been shooting black powder since I was a teenager in the 70's, but caps were always copper colored and more or less cut even at the open side. Anyone seen these before?
