By “factory” I mean factory rep in Arkansas.
now that i read your post about how you are shooting it, I’m going to guess i may be on to something.
your shotgun has an action spring coiled over the magazine tube. Its job is to return the action bar to a ready position. I’m betting the action bar connects to the breech bolt and other parts inside the receiver-those parts must move backward, which drops the carrier and allows a shell to drop on to the carrier, and the carrier then presents it upward to the breech bolt. This also draws the empty hull out of the chamber and ejects it. Then these parts must move forward to pick up the new shell. When this happens the carrier moves down out of the way. The bolt has by that point picked up the shell off the carrier and shoves it into the chamber and locks to the barrel for the next shot.
if you do not have a firm mount to the shoulder, with the butt of the gun seated firmly (not loosely) into the pocket of the shoulder, then the recoil of the gun causes backward movement that is sort of equal to the backward movement of the breech bolt. This means the bolt can’t reach its end travel point because the end point is now moving backward with the bolt. The bolt will then try to return to battery without having completed its full travel path, causing a jam like the one you describe.
Shooters that are unfamiliar with long recoil style actions encounter this problem sometimes. Working on a more solid mount usually corrects this.
