This is the ammunition used.
The shotgun is a weapon used by Michael Rosen and his mum, which has been used for defense against tyrannic demons and committing mass homicide. It is a Benelli M4 Super 90(or M1014) shotgun with a pistol grip and 7+1 internal tube that fires 2.75 shells. While it is very big, many shotgun users are specially trained and are able to harbor one inside their rectum.
