Shotguns neither fire bullets, nor do they use clips. The capacity for each shotgun will vary by model, load, and magazine. A Remington 870 off-the-shelf holds five rounds. The Saiga shotgun uses a detachable box magazine which may hold anywhere from five to 30 shotgun shells.
IZ shotguns, also the Baikal brand use the TruChoke system sold also by Colonial Arms. This is the same choke style used by the Remington Spartan line while Remington owned the rights to the Baikal design.
the rumor is any serial number on an 870 express ending with an M means its a magnum. I have one I bought in about 1987 and have shot thousands of three inch shells through it.
The Sweet Sixteen Shotguns were a model of the Browning A-5 Auto. They were made between 1937 and 1975. That does not appear to be a complete serial number.
