    I bought a Win Model 70 XTR (push feed) two years ago. The rifle had been glass bedded and was in 98%.

    When I shoot the rifle the bolt wants to stick and prevent me from cambering another round. If I play with it, the bolt eventually comes free.

    Groups are fine and everything else is as to be expected. What is the problem? Can it be fixed?

    This is a very important issue to me b/c I hunt with it and follow-up shots are of highest importance.

    Thanks

    Some possible causes.....

    Handloads that are overloaded can cause the brass to darn near weld itself into the chamber. A faulty batch of factory ammo could do the same thing. Check the fired brass for any sign of excessive pressure.

    The chamber itself could have a very poor finish - check it with a borescope and polishit or have it polished if that's the problem.

    Bad chamber dimensions/excessive headspace or poor bolt fit at the chamber mouth could allow the brass to bulge just above the rim, and could bind the bolt.

    nic,

    I'd get a gunsmith to take a look at this rifle. It sounds like a headspace problem,but it could be a rough or screwed up chamber. I assume that you bought it used as you said it was at 98%. This may have been a concern from the previous owner also.

    Get it looked at before something comes unglued and someone gets hurt,OKAY?
