12 guage shell?
Your shotgun was made for Sears by Stevens, and is their model 311. It should take 2.5 inch and 3 inch .410 shells.
What size shell in legnth are you asking about?
That's a Savage or Stevens model number, but it won't tell us the gauge. Any firearms dealer should be able to tell you the gauge by looking at the gun (unless it is a really unusual size) but a gunsmith can measaure the chambers and also tell you the length of shells it is supposed to use.
There is absolutely no way to answer this without seeing the gun, however, if you look carefully at the markings on the barrel it is probably marked there.
Air soft shotgun shells are the size of 12 gauge shotgun shells.
In a shotgun shell, it tells the number of round pellets that combine to make a linear inch.
Yes the stock on a Winchester Model 12 16 gauge is the same as a 20 gauge. 16 gauge,20 gauge, and 28 gauge are all the same for the Winchester Model 12. Thanks, Tim
Whether it is a Savage/Stevens of any other modern shotgun, look on the top or side of the receiver and it will give you that information. For example: on a 12 gauge it will say 2and3/4 inch only or 2 and 3/4 inch and 3inch magnum. The gauge is equal to the number of corresponding lead (as in metal) balls that it takes to equal on pound (troy)
Gauge refers specifically to the size of the rail, while scale can be used for anything. scale 1:10 means that things in the model are 1/10 the size of reality.
The Winchester 140 12 gauge has a choke barrel at 28". This is the same choke size as the 20 gauge model.
