From PS Magazine, April, 2008:
Shotgun breaching cartridge available
A 12-gauge shotgun cartridge is now available that is designed specifically to breach padlock hasps and deadbolts, knobs and hinges on wooden doors. The M1030 cartridge, NSN 1030-01475-7440, can be used with both the Mossberg 500/590 and Remington 870 shotguns. Its DODIC is AA54. It has a brown tip and the cartridge is stamped "12GA, BREACHING, M1030". The cartridge minimizes the ricochet hazards of breaching operations, but soldiers should still wear ESS land ops goggles when firing M1030s. NSN 4240-01-540-5576 brings green goggles and NSN 4240-01-540-5580 brings the desert tan version. COPYRIGHT 2008 PS Magazine

A shotgun built on a round action.
Mayweather won by tko in the 10th round
Manny "Pacman" Paquiao won by ko in round 2.
the worlds deadliest shotgun is the aa12 it is so because i can be equipped with a 12 round drum , a 30 round drum and a 32 round drum it could also be equipped woth a high explosive grenade round. it could also shoot repitedly or fully automatic this is why it is the worlds deadliest shotgun
Anything is possible.
It throws out a wall of eather lead or steel pelts in a vairing aray of gropings depending on the choke in ur shotgun
The AA12 has a 8 round magazine.
To cock a semi automatic shotgun simply insert the round you wish to use and pull the slide back then take the safety off and fire.
It would have to be a pump or semi-auto with an extended magazine tube.
Just before WII.
