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)
Your shotgun was made for Sears by Stevens, and is their model 311. It should take 2.5 inch and 3 inch .410 shells.
SHould be marked on barrel. If not, have a gunmsith check it out.
The Western Field model 30 pump action shotgun and the Stevens model 520 shotgun are one and the same firearm.Savage/Stevens made these for Montgomery Wards.The shotgun in question should show that it was chambered for the 12 gauge shotshell.The length of these shotgun shells were 2 3/4in. If your shotgun is not marked,I would have a gunsmith make a quick check of the chambering for you.This will only take a couple of minutes to do.
It's a .410 bore shotgun
1910, give or take a few years.
None. Some handguns have been made that will fire .45 Long Colt revolver rounds and .410 shotgun shells, but that does not mean that you can take any .410 shotgun and stick .45 handgun ammo in there.
Get a copy of the Gun Digest Shotgun Assembly/Disassembly manual. It should have the Mod 67.
Needs to be examined by a good gunsmith
Take it to a gunsmith to be sure.
Mine is stamped on the underside of the reciever. Take off the fore end and it should be easy to find....
Loading a pump-action shotgun is fairly simple. Open the action and hold the stock underneath your arm. Pop a shell into the action, then close the action to load your chamber. To load the magazine tube, take the next shell and push it into the action, then pin it in place using your index finger.
Shotguns come in standard sizes. If you take it to a gun shop, the man behind the counter can probably sell you the proper shells. If he can not, he can tell you what the proper size is.
