According to the Wikipedia article (though it is doubtful this is true) provided in the Related Links section, the Remington 1100 Tactical Shotgun, used in the military, holds a maximum of 8 12-guage rounds in the magizine.
Combat Basic Load for the M16 and M4 is 210 rounds. As the M4A1 is typically issued only to select units (Army Rangers, AF Para Rescue, etc.), personnel assigned this weapon would be likely to carry more than the basic load.
Depends on the shotgun- different types load differently.
The M4 is the basic weapon system for the modern infantry soldier. It is usually equipped with a M68 red dot sight. A standard combat load for a soldier carrying an M4 is 400 rounds of ammunition. Are you serious? 400 rounds is not the STANDARD combat load. The M16A4 is the standard basic weapon but is being replaced by the M4. A red dot is definitely not the standard sight.
NEVER ATTEMPT TO LOAD THE WRONG AMMUNITION INTO A FIREARM!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Do not do this
