Mosin sticky bolt

[Irishman]

I was wondering if anyone had a solution for sticky bolt on a mosin nagant? I have only fired it twice since cleaning the cosmoline out of it, and the bolt is real stiff as it heats up.

It's the cartridge case sticking.

I wrap a couple of patches over an old brush, wet with bore solvent, and scrub the inside of where the cartridge case sits. Other people use oversize brushes and even a drill to turn them (bore solvent again of course).

Some ammo is more prone to doing this.

Good luck,

Try that, and if that doesn't work, try some polishing compound or Bore Brite on patches laid on top of a bore brush or mop, and spin the brush with a drill. Don't get too agressive, though, you just want to clean and smooth, not resize. Then reclean, and avoid using the laquer coated surplus ammo, or try commercial brass ammo. It worked for me! good luck.

Think more like a huge peasant farmer the likes of which it was designed for and just hit it harder.

Because that can break the extractor. Is this site not Mosin-friendly?

You can't puss arm them, put some meat behind it.

from my experience it is the cosmoline that has been embedded over time due to storage. After you shoot for a while the pores in the metal open up and a small amount of cosmoline can seep out and be baked onto the surface, causing the stickyness. there is a very good video by iraqveteran8888 on youtube that shows proper cleaning techniques.

Cosmocain is the problem. Clean it out of your rifle, but don't snort it you'll get higher than sputnik.

When the rifle fires the cosmoline leaks out of every pore in the metal causing it to stick. And believe me you know sticky when you have to use a mallet to get ir open

thanks guys, I will try those tips!

It's plenty Mosin-friendly, but many folks use the color purple to denote that blatant sarcasm was intended.

Now subtle, uncolored sarcasm... that's a trickier beast and clearly how most people wind up taking the hook around here.


Enjoy!

And, <----these little things may also denote that jocularity is afoot.

If doing an extra through cleaning of the chamber doesn't solve the problem, there are a couple other things to try. First, pull back on the cocking knob before opening the bolt. Mosins have a short bolt handle and a very stout firing pin spring, so that will make your bolt easier to open. Also, many of the parts used were made under extreme conditions during wartime, so sometimes there are rough spots on the bolt parts. A little judicial polishing on the wear spots will really help slick things up.

Yep, these rifles won't be hurt by using a good whack on the bolt. I've watched videos of Red Army soldiers shooting and they opened the bolt by slapping upward with an open palm, and they weren't babying it.

Oh yes, very friendly. And no, it won't break an otherwise healthy extractor. There is a cut in the receiver ring that allows the extractor to snap over the rim when you chamber a round. If the case is too stuck, that cut will allow the extractor to pop off the case rim. And yes, I've had it do that. That rifle had some pitting in the chamber and there was no curing it short of re cutting the chamber.

A friend of mine has one that we used a 2x4 on occasion to knock the bolt loose, it was so tight. After he shot it and cleaned it several times it was fine.

Send it back and demand that they fix the problem. I can't believe that they would ship a precision firearm with a sticking bolt.

I would hold that guy named Lenin personally responsible.

 

[Irishman]

I may also need to talk to that Stalin character about him allowing such poor workmanship!

I have a pretty sticky Mosin, I cleaned it and it still stuck pretty good.

The problem seems to be solving itself. It used to stick after 10 or so rounds, now I have to put about 100 before it sticks. And of course, there's no need to baby it. Slap that puppy hard like the Ruskies did, it'll be just fine.

Wow, this is why i joined this sight.
I just wish i would have joined sooner.
I had a really sticky bolt on my m38. i had to work the bolt so hard, i would be sweating after five shot. Stripped it cleaned very well, and shot it again, no change.
Then someone told me the head space could be off. which i interpreted to be very bad, like soon to be grenade bad. Many of myu friend said trade it in, but icould not sleep at night knowing i put a dangerous weapon in someone elses hands. so i stripped the weapon and cut off the firing pin. no big deal, but since i thought i was junk, i decided it would be perfect for me to teach myself how to engrave. The only thing i learned is engraving is hard, and i suck at it. so the weapon is rather ugly.
not worth fixing. then i read this sight, and thought back, did i use the cheapest mil surplus ammo i could find? YES. Did i run a brass brush in the chamber to get it real clean? YES, but i did not fire it again after i cleaned it.
so i destroyed a piece of history. and it just sits in my garage and collects dust. me sad.

Whats really nice is when you pull the bolt back and the cartridge stays in the chamber...

Ah, yeah, that's when you know you have a problem.
