What is it and what's it's purpose? I got five boxes of ten each of these years ago in a grab bag sporting goods auction. They fit precisely in the chamber of a 12 Gauge. The primer pocket holds a shotgun primer perfectly. It also holds a .22 round, but I doubt it would fire the rimfire cartridge. The company is defunct, so no help there. You tell me what they are and what they were used for, and you get one free in the mail from me. I'll warn you, no one has come up with real proof of their use; just speculation.
