*Mosin Nagant Ammo Problem (Need help)

Also check to make sure you got all the cosmo out of the reciever area where the bolt locks up with the lugs...

This is often the cause of sticky bolts.

Never had a problem with my MN and about 2000 rounds of czech silvertip...

I used to have sticking problems with some of my hungarian surplus, i cleaned the chamber and cleared all the grunge out of the bolt face. What a difference!

I've had similar problems with CZECH ammo in my SKS, after it gets warm, the cases stick. The CZECH ammo is also the most corrosive ammo I've ever used!

Do as Cosmo says. I used a chamber brush mounted on a drill , dipped in a lacquer thinner and rotated slowly in the chamber. Depending on how dirty yours is it may take a several times of repeating the process, but so far it worked for me every time. As far as the Czech ammo ,this is one of most accurate 7.62x54R on the market. If you have a chance , it's good to heat up the chamber (shoot the rifle) and than clean it while warm (temperature softens the hardened cosmoline in the chamber).

I used a 12 gauge wire brush connected to a section of shotgun cleaning rod chucked into my power drill. Dipped the brush in some good ol' Hoppes number 9 and spun the drill. Repeated a couple times then used a 20 gauge mop to clean the gunk raised out of the chamber.

No more sticky bolt.

In the 70's and 80's I shot a lot of steel cased Russian ammo from the 1930's that the Finns had captured and then surplused off in the US about 1960. It was all steel cased, copper washed, and had no difficulties with extraction.

With all the surplus I've seen since 1995, the brass cased stuff is no problem, and the only rifle I can get the steel case to freely extract from is a new-condition M39.

Buy some Bulgarian, try to find some Albanian, or maybe get some brass-cased commercial, and your problem will go away.
