Neat stuff.
Several years ago I was rabbit hunting with my brothers and a guy that had a pack of beagles. While waiting for a rabbit to circle back I was standing in a harvested soy bean field and looked down and found an old shotgun shell base. All the paper was long gone except for that inside the base. At was from an old Peters shotgun shell that had a small primer surrounded by an octagon, I believe. I found it on a web sit a few years ago and it dated to about 1920.
