Actually the shotgun uses 16 gauge shells i have the same shotgun
Winchester stopped the regular production of 20 gauge in 1963 and the 20 gauge magnum shell wasn't introduced for several years later.
It is marked on the barrel.
the shotgun takes a 2 3/4 shell
Mine is a 12 gauge pump. Chambered for 3" shell.
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.
SHould be marked on barrel. If not, have a gunmsith check it out.
50-1000 USD depending on specifics.
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.
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!!!
it is a model made of a shell of electrographic electrons
It depends on the shell you fire.
12 guage shell?
