I'm posting this from another forum where the guy lent his gun to a buddy and then got it back and did not know the barrel had an obstruction. Firing the shotgun with the obstruction did the obvious to the barrel as you can see by the picture but the guy LOST 2 FINGERS!! and is extremely lucky to have lived to tell this story. Alway be certain your barrel is free of any obstruction before use. Check it safely by removing the barrel and look down the barrel from the breech end and NEVER the muzzle.
