Winchester Model 97
 
My father just bought a customized 97. It has an aftermarket barrel with a vent rib. When we went to test fire it the shells would hang in the chamber. When we did finally get the shell out the case was swelled around the top of the brass. Is the bore shot out or is it head spaced wrong?

The supplied pics really don't help much.

Can you repost them please?

Many times when guns are pieced together you run into all kinds of problems. As an example a friend of mine some years ago purchased a Winchester model 62 .22 pump. Actually the front was a model 62, but the rear was a 1890. At times it seemed like it went off by remote control. It was pretty, but dangerous little .22 to handle. Supposedly it was fixed, but he never touches it. As far as your father's '97 goes, I've never seen one like it and wouldn't be comfortable with it. I'd like to see a photo and hope you can fix the problem.

97 win
 
2nd try to post this info. The M97 as the M12 Win shotgun, requires the fitting of a new heading ring ( barrel chambering ring) when replacing the barrel. If this procedure is not done, one of the problems can be extraction. The heading ring must be reamed in place throught the barrel. I doubt if there are many gunshops today that have the proper equipment to do this. The inside of the heading ring could be smaller in diameter than the chamber. making it very difficult to extract a fired shell. Open the breach of the shotgun and stick your finger into the chamber, see if you can feel a ridge or diffrence between the heading ring and the chamber. This maybe your problem. For some reason I am not able to view the photo that was submitted. PaulJ

There is a ring around the inside of the chamber.

The older Mdl. 97s were chambered for the 2 5/8s paper roll crimp shell. The newer 12 Ga. shells are plastic 2 3/4" star crimp. The plastic star crimp will fire in the 2 5/8s chamber.
Problem is it is 1/8" too long in the 2 5/8s chamber after firing. The long star crimp is jammed in the chamber at firing. This causes an extreme and dangerous rise in chamber pressures. Many of these old guns are found with cracked receivers from this abuse. These guns need to have the chambers reamed to accommodate the longer 2 3/4" star crimp plastic shells.:)

The barrel isn't old enough to have the longer chamber in it. It is a newer action and it has the thicker wood
