I have a Winchester shotgun, serial 259567, model 12, 12 gauge. Can anyone tell me what size shell this will take? Apparently it was made in 1921. The length of the gun including the stock is 38 inches, not sure that makes any difference.

I looked around online and there seems to be a lot of confusion as to what size shell it actually takes 2/ 3/4 etc.

All 12 gauge model 12s have a 2-3/4" chamber, except for the Heavy Duck version that has 3" chamber.

I strongly suggest you have an experienced gun-smith look over a firearm of that age, before trying to shoot it. You don't want it to blow up in your face.

Did not think of that. Wise advice! Thank you!

The model 12 Winchester is one of the strongest shotguns ever made. BUT it is nearly 100 yrs old. Get it checked before you shoot it. The only place I have ever seen one show wear was the cut out on the inside, top of the receiver. That cut out is there to provide a locking point for the breech block when the breech block locks into 'Battery'.
