the gold end w/ the firing cap
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!!!
12 guage shell?
The 20-gauge shell will fall into the barrel and lodge. When a properly fitting 12-gauge shell is chambered and fired, it will blow up the barrel and you will have a very bad day.
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.
The danger is that the shell will fall forward, blocking the barrel, but allowing a 12 gauge shell to be loaded. If that is fired while the barrel is locked, the gun will likely blow up, destroying gun and injuring the shooter and innocent bystanders.
12 gauge.
A 12-gauge shotgun shell typically contains multiple pellets, which are small, round projectiles inside the shell. The number of pellets in a 12-gauge 3" shell can vary depending on the specific type of shot being used, such as birdshot or buckshot. As a general guideline, a standard 12-gauge 3" shell with birdshot may contain around 1-1/8 to 1-1/4 ounces of shot, which can translate to roughly 200 to 300 pellets. For buckshot, there are typically fewer but larger pellets, with a 12-gauge 3" shell commonly holding around 8 to 15 pellets.
7000
Depends on the gauge of the shell. The smaller the number, the bigger the shell. A 12 g shell is ABOUT 3/4 of an inch in diameter.
.5 -1.5 oz
SHould be marked on barrel. If not, have a gunmsith check it out.
the shotgun takes a 2 3/4 shell
