This is a DUMB thing to do. It may work a few times but sooner or later you WILL blow up your choke and barrel and maybe yourself. It's kinda like shooting a 10 gauge shell in a 12 gauge gun (if you could). I've a freind that used a year or two old BBB steel shell that had rusted together from lying in his boat. He shot at a goose from a field blind and blew his choke and barrel to bits. Your trying to do the same thing because if the choke doesn't strip the hull from the payload, it ain't fit through the choke and Blewwy. It's a sound you won't soon forget either !! Good luck :roll:
