Model 12 Winchester stuck shell

riley p
Mid way through a sporting clays match my trusty Model 12 let me down. Fired shells were getting stuck in the chamber. The extractor is fine and I use strictly factory shells. At first I though the headspacing ring some-how got eccentric to the barrel part of the chamber but on close exam it doesn't seem so. Does anyone out there have any idea what is going on or know a Model 12 doctor who can help?

    Have seen this several times. Are you using shells with a "high Brass" on the shell. I saw it with Federal paper shells where the brass swelled in front of the chamber ring and then could not be extracted. Try some shells with a low brass, such double A's or Remington STS. If thats the problem then your're going to have a knowledgable gunsmith check the chamber and chambe ring and match the ring to the chamber.

    The shells weren't what I'd call hi-brass. Walmart or K-mart 1 oz Remington loads or similar. Do you think a gunsmith running a chamber reamer up through will solve the problem?

    Hello riley! Well my first guess would be, the type of shells. As Bt99 said try a different brand. Some shells today, only have the base of the shell brass coated. Also in the case of paper hulled shells, they just hang up every now and then. Now I'm assuming this is a pre-64 Md 12 so it's at least 40 years old, and depending on it's care over the years it could have a few worn areas. Yes I do know a very good "Md 12 Doctor" an exgunsmith from Winchester. Has all the right tools to replace the chamber ring, and adjusting sleeve, check the timing and head space issues. Just email me, click on only winchesters to the left for his web site. Regards Dave

    I'd be really surprised if, in this day and age, you are shooting paper-hulled shells--they're more than likely plastic. And, in the quantity you shoot them, and as hot as skeet/traps guns get, you have probably built up plastic residue in the chamber of your shotgun; not always readily visible to the unaided eye. You should probably start with a thorough cleaning of the chamber using one of several gun cleaning products on the market advertised specifically to remove plastic residue. If you still experience sticking you could have the chamber polished, but under no circumstances should you insert a reamer. I'm betting that a good cleaning will solve your problem.

    Nope, it ain't dirty. I treat my guns better than family. (They're less likely to let me down) thanks, anyway

    Actually paper shells are still quite popular in trap shooting. I had to quit shooting trap due to back injury, but when I was shooting I used nothing but Federal paper target loads. Best shell ever made.
    Federal still loads them in the 117 line.

    Hello "riley p"[:)]

    I would suggest you get in contact with someone who really knows "Winchester Model - 12's" inside out and unside-down, & backwards.

    That would be the former "vice-president" of marketing for Winchester.

    His name is James C. Gates---who is retired and now resides in Old Town, Florida. He is also the owner of "dixieslugs.com". He is the moderator of the reloading forum on "ShotgunWorld.com". His e-mail address is jcgates@bellsouth.net.

    He has forgotten more about "Winchester's" than the rest of us will ever know.

    My Best Regards To You And Your's During The Holiday Season:[:)]

    As someone said before....residue or scarring of the chamber, seperate the barrel from receiver, chuck a bronze brush of proper guage in a hand drill, wrap the brush with some 0000 steel wool, rotate in the chamber until shiny, examine the shiny chamber for mars....if none are visible, the problem was most likely residue from burned powder and shell casings, ordinary cleaning techniques will not always remove ALL deposits.
