I have an old westernfield 12 gauge. It is identical to a Mossberg 500 but branded under the sears westernfield name. My question is: how do I know if this is chambered to shoot 3 inch shells? Is there a way to tell?
It should be stamped on the barrel, near/on the chamber of the barrel. If not and the shotgun is "that" old, I would assume that it's a 2 3/4" chamber. Better to go small and be safe, not sorry.
just because the barrel says 3" you put on doesn't mean it will eject a 3" shell, the receiver may not be set up for 3" shells try taking a dummy round or a 3" snap cap ( please do not use live ammo- ) put it in the magazine and feed it through the gun to see if it functions properly. I used to have one of those years ago -but I purchased it without a barrel and I made a barrel for it to go to the turkey shoot in 2 3/4 " and it worked fine- I don't think it will eject 3" shells. please let me know if it does. have a nice day !
