Air soft shotgun shells are the size of 12 gauge shotgun shells.
the shotgun takes a 2 3/4 shell
it is not safe to fire 16 gauge shell in anything but a 16 gauge.No shells will interchange with other gauge guns since a 16 gauge shell would fit in a 12 gauge chamber, I would think you can do this.
NO!!! A 12 gauge shotgun takes only 12 gauge shells. A 20 gauge shell would fall into the barrel and get stuck about half way to the muzzle. You would be in for a nasty surprise when you put a 12 gauge shell behind it and pulled the trigger!!!
Yes, if you eject it into a roaring fire.
The best shotgun shell for shooting ducks is a 3 to 3 1/2 inch 12 gauge with number 2 shot.
Most 12 gauge shotguns are capable of shooting the 3.5 inch shotgun shell. It fires at around 14,500 PSI.
This is a shotgun with an internal barrel diameter (called the "bore) of approximately .410" which shoots a shell which is about .410" in diameter. It is the only shotgun shell size that uses this convention. A 12 gauge shotgun, for example, does not have a bore of "12". A 20 gauge shotgun has a smaller bore than a 12 gauge and a 10 gauge has a bigger bore than a 12. Gauge size is based on the number of lead balls of the bore diameter which are required to make a pound (16 ounces). 10 balls, 12 balls, or 20 balls.

Yes. The Mossberg 500A1 is a .12 gauge shotgun.
If your shotgun is a 12 gauge pump, then you have a High Standard Model 200 (Flite King). The standard 12 gauge shell is a 2 3/4 inch shotgun shell. It can be anything from #8 birdshot to a deer slug.
