M44 Problem

[rshinjiro]

I've actually run into this exact same problem with my M44, tried different ammo, brass case, steel case, always the same result. Headspacing checks out, extractor is grabbing. Chambers a fresh round fine, then after firing wont eject without some nudging. Curious to find out if what fixes this for you will work for mine as well.

i have had the same problems with a few of mine, the problem in my case was that there was cosmo on chamber walls that had been cooked on there. I took the gun apart and heated the outside of the chamber with a propane torch untill it was warm and used a stiff cleaning brush and scrubbed the hell out of the chamber. after doing this about 3 or 4 times it was sqeaky clean and didn't have any problems after, also soak the bolt in some cleaner for atleast a few hours then go to town cleaning the bolt, should not have any problems after that.

This makes the most sense to me. Love it when guys use the "blast it clean" method when they first get a cosmo covered C&R. I'm going to assume you didn't do it. Curious as to how this turns out OHOD.

Try to loosen the screws holding the trigger guard/magazine assembly down.

I had to shim mine down away from the bolt.

and this was on my Romainan M44.

Worked AWESOME afterwards.


EDIT: This sounds like two problems in this thread. My posting above is to the original poster about the closing of the bolt the last 1/4 inch. and it hanging up on the way out.

Looks like the extractor is a little dinked up. Not sure if that's the prob.

The flat spot on the leading angle of the extractor may be jamming on the rim. Thus pushing it backwards in the boltface to the point where it no longer has the clearance to hold onto the rim.You can file to restore the angle a bit. Or if you dont want to bugger the original, get a new one

When a shell is in place the extractor will more or less be flush with the back of the bolthead. If its binding it will be pushed back and protrude. You can test this.

Yup looks like the extractor is pushed back. It's supposed to be flush with the back of the bolt head. Tap it back into place and chamber a round and see if the extractor gets pushed back.

I had a problem with failure to close on a round AND the rare moments it did close, after firing, failure to open bolt without the help of a rubber mallet.

My extractor looked worse, its tip was flat and a case could not sit nearly as flat on the bolt face. Since I was ready to change out the extactor I went ahead and modded it to mimick other Mosin bolts. It works fine now every time! Good luck on this, I know you won't need it as you'll come through victoriously!

I have some potential solutions.

1. I'm going to check headspace with a gauge Rem222 is going to let me borrow.
2. Try to get the extractor flush with the bolt.
3. Go over Bruceflinches place and work on it. Enlist the help of Big103 as well.

Hammer, very large hammer....works with computers as well.

Most Russian problems are solved this way comrade.

[bruceflinch]

I have a 3lb hammer. Is that big enough?

[big103]

Yeah looks like the back of the extractor needs to be taken off a little.

Came across a thread from surplusrifle which seems to describe this problem and solution well.
