    Murdaugh murder case - defendant grabbed a 12 ga Benelli auto shotgun and leaned it against his car. Cops found one 12 ga and one 16 ga round unfired in the gun. Lawyer asked, what would happen if 16 ga were attempted to be fired in a 12 ga gun? She didn't know. Anyone know? Would it fire? Rupture?

    I’ve cycled and shot a 20ga & 16ga through my 12ga 870 just to see what would happen.

    16ga no problem in the magazine tube, cycled, fired didn’t fully extract or eject.

    20 ga would cycle through the magazine tube and didn’t fire.

    I imagine a 16 in a 12ga or a 20 in a 16ga shotgun would swell initially but still fire the load and be lethal. There shouldn’t be any damage to the gun as the pressures wouldn’t be any greater than the gun would normally see. The shell may rupture and be difficult to remove if the brass swells enough.
    Anybody see the vid of the guy shooting a 50 BMG from a 12ga?

    Did it accidentally in a mossberg pump gun. Loaded in tube fine, cycled into chamber fine. No bang when I pulled trigger.
    Thought it was a malfunction, did same again and then realized it was a 16 shell.
