I have this shotgun which jams after each firing; I can load it up with shells and pump them all through the chamber with smooth ejections everytime on a dry run but as soon as I fire off a round the shell binds in the barrel preventing the breach from opening and ejecting the shell. I have cleaned it well and find no visible damage to the brass once I get the gun unjammed. There is no real change in the diameter of the brass except for a few thousands. The spent shell goes into the barrel freely so I am at a dead end so far. Has anyone ever had similar problems with similar symptoms to help me diagnose this problem.
