I have a 1943 Mosin-Nagant sniper rifle that chambers and extracts an unfired round with no problems, but when a round is fired, it is very difficult to extract the round.....any suggestions on how to resolve this problem?

Is your chamber cleaned really good. Sounds like there may be buildup in the chamber and when the round fires, the case expands in the chamber and sticks.

I will check it for that....thanks for your response !!!

That's just a characteristic of the gun. Slap her around like a dirty Russian. I've heard of people trimming the spring on the firing pin but I haven't done it and wouldnt wanna risk it personally. Like I said just slap it around.

I also have a 1943 Mosin (though it's not the sniper model) and it has this problem occasionally. The bolt will open partially, but then reaches a stopping point. When this happens, I hit the bolt lightly with the open palm of my hand. It then opens completely and I can eject the spent round.

I think my rifle is fine; I've been blaming the Bulgarian military ammo that I'm using that was produced in the 70s. I'll be watching this thread to see what else gets posted about this; I've been curious about it, too.

I just joined this website and asked this question without looking at the entire forum. After looking a little, I see that I'm not the only one who has had this problem, so it seems that it has already been addressed and there are some good ideas that have been presented. I had no idea how much information is available on this forum....I'm hooked !!!

I have a1942 91/30 and after a good cleaning in the chamber and using a plastic pick to dig out all the old cosmoline and soaking the chamber in Breakfree CLP overnight, a 20ga bore brush and a 12ga mop. Polished most of the bolt and knocked off some of the really rough edges with a jewlers file. My bolt cycles better than my other bolt guns and locks up solid.

Mosin Nagant is a battlefield weapon, not a precision hunting rifle. The bolt is a bit stiff but responds well to a brisk upward palm slap to eject, cock and rechamber a round...no need to gently cycle the bolt. Just make sure all the cosmoline is out of the chamber and the bolt is well lubed.

When I got mine it had the same problem what I did was I took a brass cleaning rode and put the wire brush on it put it in a cordless drill and ran it through the chamber after that I didn't have any problems with it.

Your not going to hurt the rifle, so just give the bolt a nice firm whack with your palm. Mine tends to tighten up on me when it get pretty hot. A good firm whack solves that problem.

I followed the advice given by other members along with the video posted on youtube and cleaned the chamber with a 20 ga brush coated with JB bore cleaner using a drill and cleaning rod. Then followed that up with a 12 ga mop. I also polished the firing pin using 600 grit sandpaper. After cleaning everything up...the gun shoots and ejects the shells as smooth as silk. Thanks for everyones help !!!

The firing pin spring would have nothing to do with the described problem.

Most likely, in order are: dirty chamber, dirty chamber and dirty chamber. There are other rare instances of burs or other problems but removal of 60 years of dried comsmoline, varnish, and who knows what else usually fixes the problem.
