Mosin Nagant - Feeding Problem

[Ubergeek]

In brief:

1. Load 5 rounds in the magazine.
2. bolt picks up the top round and it goes into the chamber with no problems
3. open the bolt, spent casing is extracted and ejected with no problems
4. second round is still being held in place in the magazine by the interrupter, user has to push on the ejector to get the interrupter to release the round

Repeat 2-4 until you get frustrated enough to put the rifle away for the day.

The ejector doesn't seem to be under extraordinary spring tension (compared to another Mosin Nagant that doesn't have this problem), nor does it appear to be obviously mis-shaped (bolt slides easily over it).

I suspect a bad extractor (doesn't hold the casing in tight enough to depress the ejector fully).

Anyone here have any insights? Thanks in advance.

loosen the magazine from the stock, might be a bit tight

There's also a chance that you have the interrupter installed backwards or improperly aligned (its hard to do but someone may have screwed it up at some point.

I'd pull the rifle apart and look at the interrupter mechanism if you need a pic of what one looks like when correct I can take one of mine apart and photograph it for you.

I love the Mosin Nagant, but all the ones I have except for my M44 have occasional feed problems. It can have something to do with the fact that the cartridge is rimmed. Rimmed rounds have inherent feed difficulties. Read about the trouble that the Brits had when they were looking for automatic weapons that could fire the .303. Its not an accident that by WWII only two major powers were still using rimmed ammo. Hell, even most 3rd world countries at the time were using rimless.

Once in a while mine sticks if I baby the bolt too much. Have you tried working the bolt fast, that usually does it for me?

The bolt pushes on the interrupter, nothing to do with the extractor. It gets pushed when the bolt is turned, IIRC. If it's working right, you should be able to push 4 down below the interrupter, close the bolt, open it and chamber a round.

Here's a good video that shows how it works: http://video.google.com/videoplay?do...arch&plindex=0

Everyone -

Many thanks for the suggestions. The video was very useful in helping me to understand how the interrupter is actuated.
