mosin nagant bolt problem

[chillincody]

so my question which i know someone here will have a answer to is... i went shooting with my friend he brought his mosin out so i can shoot it an see if i want one or not but after about 20 rounds bolt started jamming bad and the more rounds the harder the bolt got .so id this something that can be first by cleaning and grease or something or is it just a problem the mosins have any help would be so awesome.

do you mean the bolt became difficult to lift and operate? if so, "Sticky Bolt" can be attributed to a couple of problems.

1. cosmoline in the bolt. take it apart and clean thoroughly. some people like to put the bolt pieces in a pot of boiling water to get all the cosmoline off. dry and oil well after that though

2. could be ammo. is it lacquered cased ammo? some Mosins will have sticky bolt when using that.

3. dirty chamber. clean that thoroughly as well

im not sure what ammo we were using it had a weird tarnish look to it and i didnt think about the cosmoline im betting its that. i love my friend but hes notorious for cleaning half *** lol so ill clean it for him is there a certain lube recommende or will normal gun oil be fine (remington gun oil)

What you experienced is referred to as the "Mosin sticky bolt syndrome".
It seems to be caused by old baked on Cosmoline in the chamber or varnish from steel cased ammo.

Here are some links that might help.

i use Kleen Bore oil on my bolts and it works fine

If he's using surplus, make sure he uses Hopes #9 or similar to get the corrosive residue after shooting.

man i love you cal gunners thanks again

[chillincody]

yeah we both use hoppes 9 i like it works great and under 4$ lol but might pick up kleen bore or bore bright for this

If you are using corrosive ammo. you need to clean with plain old water to get rid of the salt residue -- then your hoppes or other favorite brew.
