The cartridges will pop out.
I happen to have one or two and I think they are worth $450-$650 depending on condition.
I happen to be in the same predicament. Its a double barrell nickel plated 12 guage made by T.B. Janney with Twist Belgium on the barrell. Any info...? colby.carter@hotmail
Nothing assuming that the barrel is at least 18 inches at you haven't committed a crime with it.
It could either push the sword out of the barrel, or cause the bullet to deform to the point where it created a barrel blockage. There is a possibility that it could cause the barrel to burst, but it's much less common than some people are led to believe, as the steel used in the barrels is much stronger than people tend to realise.
Heavy Barrel happened in 1987.
Operation Barrel Roll happened in 1969.
Donkey Kong Barrel Blast happened in 2007.
I had this happen to me today. Even worse, I attempted to twist my rod out....It worked. The rod came out leaving the cleaning pad and jag still in the barrel. I have ordered a CO2 discharger from cabellas and am hoping to blow the jag and patch out through the touch hole.
Improper performance.
It will also double.
Double Dunk happened in 1989.
Double Axle happened in 1991.
