Hey Guys. I recently picked up an Ithaca Mag-10 with the 32" fixed full choke barrel. I fully planned to shoot Bismuth through it until I compared it to my friends Mag-10. The wall thickness at the muzzle is thicker than my friend's. He also has an SP-10 that had to be cut down when his hunting partner blew out the end using steel shot with a full choke. I don't want my gun to end up like that. My question is this: Did Ithaca make any of the full-choked Mag-10's to shoot steel shot? Since Ithaca is Out-Of-Commission I cannot ask them, obviously, so any help you guys can give me would be greatly appreciated.
