Mauser drops round while extracting.

[kfd518]

Mauser action is dropping round out during ejection. As soon as the round is clear of the ring it drops back down into of magazine instead of holding until it reaches the ejector. I have replaced the extractor and it still does the same thing. Does anyone know of a way to remedy this?

The Mauser has a positive ejector, which is a spring-driven pivoting piece of metal attached to the left rear of the receiver, that moves in behind the case as the bolt is operated,

When the cartridge case, which should be held in place on the bolt via a combination of the extractor's grip on the cartridge rim, and the small rim around the bolt face, impacts the extended ejector and gets pivoted out of the receiver.

If your Mauser is not ejecting, then there could be a variety of reasons:

1) Foreign matter in the bolt face is not allowing the base/rim of the cartridge to fully seat inside the circular edge of the bolt face - clean it in the angle of the boltface rim and the boltface itself.

2) The ejector is either not in the gun, is broken off short (the tip), or bent, so that it can not slide into the cut on the left locking lug when the bolt is withdrawn to the rear - replace the entire unit.(bolt stop, ejector & EJ spring)

3) The EJ spring is missing, broken , or has lost its springiness - replace the entire unit, as above.

4) The bolt is not being moved all the way to the rear, either from short-stroking or interference from a bent/broken EJ plate.

5) Since there are different Mauser extractors available (they all look almost identical, but are not), it could be that the wrong extractor(s) have been installed.

Wow! Just wanted to comment on the amount of experience and brain power on this board never ceases to amaze me. I have a Mauser that is torn down at the moment for a project and will have to now look at the entire ejection processes to understand what I just read. Thanks to all who take the time.

#5 I believe may be the problem I was not aware of variation in extractor types. The one I replaced it with has what appears to be an anchor stamped at the tail end of it. Any idea what this would have been made for?

It seems that as soon as the cartridge clears the front ring it just drops out of the extractor and off the bolt face. It never makes it back to the ejector to be thrown clear.

What action do you have? If you have one of the Yugo Mausers with a 98 extractor then that is your problem. Also you might have one of the 91,93,95 Mausers extractor. Most of the extractors will fit but not work properly. More info needed.

Did someone alter the extractor to "jump" the rim when single loaded directly into the chamber and grind it so short that it does not hold the case against the opposite side of the bolt face?

Is the side opposite the extractor extremely worn and rounded therefore not supporting the case against the extractor?

This is pretty far out, but is it possible that the bolt face has been altered to MAG?

You need the extractor for the 24. The VZ24 is a medium length action and takes a shorter extractor. If you just buy a "Mauser extractor" then it is most likely for the long action 98,turks, etc. If that is the case then that explains the case dropping before ejection. E-sarco.com had the correct part a few days ago. Should still have some.

[Rojelio]

VZ-24 is a standard length 98 action. Your replacement extractor is probably for an argentine 98 which is a little different than a standard 98 extractor because the rim is thicker on the 7.65x53.

One question. Is your rifle still in it's original chambering?

One question. Is your rifle still in it's original chambering? is the anchor stamp marking an argentine extractor? Guessing the tip is shorter on argentine vs standard? It is now chambered in 35 whelen but it does not hold any 30- family cartridge

Yes, just checked 2 of my Argentine mausers and they both have the anchor on the very end. Not sure if the claw is shorter but there is more clearance between the extractor and the bolt face to allow for the thicker rim of the 7.65x53. Therefore it doesn't hold the cartridge tight enough to allow proper extraction.

Take the bolt out and slide a rim under the extractor. The case should kind of snap into position and be held up by the extractor tension. If not, it could be the shape of the hook or lack of spring tension. The edge of the hook should be slightly crescent shape. If the hook is to open on the bottom it will push the cartridge down. It's not easy to add material, so a different extractor may be in order. Some extractors lose their tension from being removed, but it is an easy fix. Remove it, bend the tail of the extractor toward the bolt so it has more tension upon reassembly. When reassembling, only flex it enough to install. It is hard to explain in writing, but I hope you can understand what I'm trying to say.

PS edit. It looks like the above post may be on to something. The hook has to be close enough to the bolt face to hold the rim against the opposite edge of the bolt. But not so close as to prevent a round from tipping in out of the magazine.

FYI, the usual method is to relieve the receiver wall, rather than weaken the spring

I don't understand what you mean by "relieve the receiver wall".

[waksupi]

Think about where the end of the extractor contacts as the cartridge is pushed home. There needs to be enough relief to allow the extractor to over ride the rim as it is chambered.

Check dimensions in 8!mm Mauser vs 7.65 argentine.
Argentine extractor rim groove appears to be .3 mm thinner than 8mm
Argentine case head appears to be .1 mm narrower
Argentine Extractor groove width appears to be .1 mm wider.
The groove width is where I would imagine to be a problem.
Either way my cartridge is not held tight on the bolt face. Can anyone recommend an extractor that would give a tighter fit or can someone take some measurements of extractor hooks they have on hand.

[kfd518]

The extractor currently in it is unaltered brand new.
The only modification done to the original was relieving the bottom edge of the extractor. I imagine this was done to help feed cartridges at one point in time from the right side of magazine.

I'd order a vz24 extractor from Sarco or Numrich and go from there if you haven't already.
Best, Thomas.

[kfd518]

It seems it will grip R P 270 head stamps. It will not grip hornady or R P 35 whelen head stamp though.

[Texas by God]

In that case try 30-06 brass. Find a brand that fits then form those to .35 Whelen.

Just so happens these are formed to 35 already just need to get dies and projectiles.

[kfd518]

Well now I'm getting somewhere I measured the various brass I have here and it will grip 0.4070 but not 0.3945 I am trying to figure what the smallest cross measure of rim size and extractor groove it will grip is then I can just base brass off of that in the future. It seems a lot of new brass is not made to max spec especially with most rifles being push feed it doesn't matter now. I believe that a deeper (smaller diameter) extractor ring might almost be advantageous with Saami and Rem style extractors.

sounds like the bolt face might be worn a bit..i have fixed mausers that were worn out on the bolt face.. you can either take a little metal off the extractor where it rides on the bolt to close the gap up a little if there is room, or in extreme situations the bolt face will have to be welded up and remachined to tighten it up.. i got a mauser i did this to. it was so loose that even by closing up the extractor gap it would just drop the round back in the chamber.. i had to weld up the face and put the bolt in my mill with a endmill the size of the rim of the cartridge cases i am using. rifle was worn as frack when i got it like it had a million rounds sent through it.. the way i got it setup now also turned it into a fully enclosed safety action. the cartridge ride pretty deep into the barrel when the bolt is closed and when the bolt is closed it is almost bottomed out on the barrel face and this fully encloses the cartridge case.. this supports the cartridge case all the way to the rim and makes everything a lot stronger with less chance of case rupture.. but i would try to close up the gap first by taking a little off the spring at the bolt face where it rides on the bolt..

I think all the extractors for Mausers are like the 98. Bolts may be different but extractor is the same. Correct me if I am misinformed.
I have replaced min and it still drops rounds. One solution is to work it like a Mauser. Fast and hard.

[wrench man]

My M-48 does this, replacing the extractor claw did not change the issue?, I'm convinced the it's the bolt face, there seems to be insufficient material to support the cartridge rim opposite the claw?

"One solution is to work it like a Mauser. Fast and hard."


Very true. Try to baby a Mauser, and they get pouty. Work it like a Mauser was designed to be operated, and a lot of problems are cured. I fully expect my ejected cases to go around five yards before hitting the ground.

[kfd518]

I believe I have found the issue on mine, there is a west lip on the bolt where the dovetailed portion of the extractor fits in the bolt. When slid all the way back it holds tight. But push forward as if on the extraction stroke and it looses the tension that was there.
Work it like a freight train and it seems to do a decent job.
