So when I first got my mosin, it cycled just fine. It was a little stiff but completely manageable without any real effort. I then went on to polish my mosin bolt. After I did this, it started to freeze up after I cycle the bolt a few times. I would work it and it would progressively get harder until it is completely unmanageable. I have taken the bolt assembly apart multiple times and polished the contact surfaces each time but no matter what I do, it doesn't fix it. Anyone know how to fix this problem?
