Winchester Single Shot Problem

    Hello again.

    A good buddy of mine just picked up an old Winchester single shot carbine. I believe the model is 60a or 67a, I can't remember which.

    Anyway, We took it out back and started shooting it. When it was my turn to shoot, I put the gun up and fired. I got a small puff of warm gas in my face as the little gun fired. I handed the gun back to my buddy and asked if he had felt the same "puff." He said yes. I told him that it would probably be a good idea to put that one up until we can find out the problem.

    So, what do you think? It is a very simple action. I tore it apart and looked at it, and everything seems in order. The only thing I can think of is that the bolt may not be long enough by a split hair and is letting gas bow back.

    Please tell me what you think and what a possible solution may be.

    Howdy skofnung,

    I'm not familiar with the rifle in question, but I'll take a shot at it and say
    that it sounds like a loose lockup at the breech is letting the gasses get by
    and into your face. Not a good thing to have happen.

    If it's a break-down type action like a shotgun, it's a pretty easy fix. If it's
    a rotating or camming bolt, it may not be. Best advice that I can give is
    to let a gunsmith check it out and advise you on whether it can be repaired
    or should be retired to wall-hangin' status.

    Thanks Mr. Tuner. It is indeed a bolt action. What would the options be? A slightly longer bolt?

    I don't know who would want this thing hanging on their wall. It looks like something made in a middle school shop class. It needs to shoot in order to justify it's existence.

    Thanks again.

    Tough call...may be that the barrel shoulder needs to be set back to correct
    the headspace...May be that the chamber is out of spec...Maybe the
    bolt lugs are worn out.

    ROFL on your comment about justifying its existence. That was classic.
    :D :cool:
  5. I would look to see that the round is fully seated in the chamber. If there is some crud keeping the bolt from fully seating into the chamber, that could be causing the problem. If someone was only shooting shorts or cb caps, it is possible that a ring may have built up in the chamber, not allowing the LR case to fully seat. A quick clean up with a .22 rim fire chamber reamer just might clear up the problem. A quick check with a no go guage would confirm if the chamber was cut too deep also.
    Good shooting, john k
