Mosin Nagant...

I have purchased a Mosin Nagant. I am sure it will come full of cosmoline. What is the best method to remove this from the metal parts and from the wood stock?

As a fellow Mosin Nagant owner, I am familiar with your sticky situation. First step-Pull the stock from the barreled action. Pretty simple, 2 screws and the 2 bands on the forend. Step 2-gently heat the stock, either in the oven (140-150 deg) and occasionally wipe it off as the cosmo beads up or use a heat lamp or heat gun. Keep the heat gun or lamp moving so the stock doesnt scorch. Takes a while, and the wife will complain about the smell. I kinda like it!!!
For the barreled action, hose it down with carb cleaner inside and out, and scrub away with a brass bore brush. clean and oil it afterwards. Pay special attention to the chamber to remove any hardened cosmoline, it can cause the bolt to stick after firing. PS, gunsmith on vacation, hope this helps u out

I'm divorced, she complained too much already... I wonder how low I can run the oven... 140 seems kinda high... Welp, I will see how bad it is when it comes in... wipe it down every 10 minutes for an hour? Would a parts solvent do the same thing? let it soak overnight?

I would avoid solvent on the stock, sweating it out works pretty well. using a clamp on heat lamp works well, you can vary the height to adjust the heat. get one at a pet store, used for snakes and reptiles.

Ok, the Cosmoline came in today, I am sure I will find a rifle somewhere...
Gun actually looks to be pristine after wiping in down with paper towels. Wood stock appears new or refinished. Of course if I could see down the bore I'd know more. But the rifle looks outstanding as far as condition goes.
I'll know more when I take it apart and clean all the metal parts. The wood will take some time.

Ok, I soaked all the metal parts in Mineral Spirits and cleaned them with a toothbrush. I then re-assembled the bolt. I then sweated out lots of cosmoline from the wood. I used a hair dryer. I figure this is pass one, and it will need it again. I then reassembled the rifle. All the serial numbers match, except for the bayonet. The bayonet lock in place seems to work fine, but the bayonet is too tight for the rifle. Gurrr... It will require some honing or a tapered metal bar to open it up. The bolt also seems very tight and hard to work. I am pretty sure I put enough gun oil on it. The rifle looks to be in great shape.
Now I just want to make sure the gun is safe to shoot. Of course I don't have any ammo for this either. Maybe on Sunday I will take it up to St. McMiller and pray with it.

I didn't think of that. It was really pretty easy. Completely strip the Mosin, disassemble the bolt, and all metal parts. I took a 2" deep baking pan, placed all the metal parts in it covered them with mineral spirits ($12 Home depot), then covered the pan with aluminum foil. Plugged the barrel with a small rubber stopper, and then filled it with mineral spirits. The next day I drained the barrel. Scrubbed the receiver with a small toothbrush. Then cleaned the bore with a copper solvent, then with good old CLP. There seemed to be a ton of black removed with the copper cleaner. Then I scrubbed all the other metal parts in the mineral spirits with a toothbrush. Then I let all the metal parts dry.
Next I took the hairdryer to the stock and heated the stock till it was pretty hot and the cosmoline beaded up. Then wiped it down. Repeated a couple times. Then lightly oiled the metal parts and reassembled the entire rifle.
The only tricky part is making sure you properly align the firing pin. The rifle's cleaning kit came with a tool for doing this.
I think it's range ready.
