Mosin Stuck Casings

[demogorii]

I took it out shooting again after leaving it soak in hoppes, but that was before I read your comments. I will examine the chamber more closely. Its a little bit better than last time. I believe with time I'll get it working. Next thing I try is the brush on a drill.

Thanks all, I'll give updates after I try this.

I still had issues with sticky bolt after doing what you recommended. I also tried soaking a thin patch with solvent and locking the bolt on it and left it soak over night. I then cleaned it with Q-tips in every corner.

Turns out after very close inspection of the chamber, there was a burr. I was able to locate it by coating a spent casing with metal blue, pushing it tight in the chamber and then getting it out with a rod. The area where it was scratching was then exposed. I realised that I wasn't even able to extract dry-fired spent casings with the bolt (thus eliminating the cosmoline theory). I took out a Dremel with a small metal buffing bit and some buffing compound and slowly I was able to remove the burr. Now spend casings will extract after dry-firing on them. I am confident that next time I go to the range it will extract. I'll let you guys know if it still doesn't.

Thanks a lot!

It sounds like you have it figured out. One recommendation for you though. When you are firing at the range and you have a difficult time opening the bolt after firing. Pull back on the cocking knob and then try to open the bolt. You'll notice a difference. Good luck.

Thanks for keeping us up to date. Let us know how the next trip to the range goes.

Your endeavor to repair your rifle inspired me to join these forums in 2022. Having the EXACT same issues on my 1934 Model 1891/30. Brass extracts fine but steel casing does not. Going to attempt to boil my bolt and star chamber and clean it it properly, maybe even use a drill. The burr you mentioned, if you are still in these forums, was located where exactly?
