Blackheart, did you see the picture I posted? That's a full sized 2 and 3/4" 12 gauge shell, and I didn't stage that picture. It happened three times just from racking the action with a loaded magazine. The third time it happened, I laid it down in my gun case and took a picture of it to show my gunsmith. Same thing happened to Hickock45 while reviewing a Mossberg pump shotgun. If it were impossible, it would not have happened three times to me, and been captured once in a Hickok45 video. He was using standard 2 and 3/4" shells, too.
Did you check to see exactly how/why it was able to happen ? It's certainly not the norm or at all common for a Mossberg to do that. Was the shell stop portion of the trigger guard broken, deformed or missing ? How about the extended tab on the bottom front of the elevator ? All check out ? Did you compare parts with another Mossberg that functions correctly ? I haven't seen that particular Hickock45 video but have seen enough flubs on his other videos with various guns to know he's a boob not well versed in the operation or mechanics of many of the guns he tests.
