I am not a Mauser expert by any means and I don't know how to diagnose this problem. I presume the extractor needs replacing.

The rifle is a vz. 24 from 1926 and was not refurbished. The bolt matches the rifle. The extractor appears to have a very slight bevel but it will not slide over the rim of a chambered round and must be fed from the magazine as per usual so I'm guessing the bevel was from the factory. I am not trying to close the bolt over a round in the chamber, I am feeding from the magazine. I am just trying to illustrate that the bevel wasn't for this purpose.

Here is the problem: Sometimes though, the extractor rotates slightly to the left and won't fit into the machined groove in the receiver when I am working the action. I need to slam the bolt home to force it in or push the extractor back down. Other times it doesn't feel like it's closing over the rim as soon as other 98 pattern rifles I own while it's picking a round up from the magazine.

Any help is appreciated.

Careful! These gems don't like pushing onto a chambered round. Let the bolt strip the round off the magazine while closing and extractor is neatly in place, while pushing round into the chamber. Designed that way. Trying pushing the bolt into place and troubles will follow! That extractor is well designed to pull, not push.

VZ24 are nice Mausers (possibly nicest of warrior '98s)

I am not trying to push the bolt over a chambered round. I was just trying to explain that while the extractor is very slightly bevelled, it was not bevelled to allow closing over a round in the chamber for single shot loading, as many were. The problem is occurring with rounds coming out of the magazine.

Your posts read as if you have a round in the chamber, and are trying to close a bolt on it. Don't do this with Mausers with that sort of extractor. It'll break the extractor, or possibly deform the round, or just be miserable to close until it breaks the extractor.

If you're having issues with single/last round being striped from the magazine, it may not be the extractors fault. Follower, weak/backwards magazine spring. Always cycle your bolt action 'surps smartly. Cycling them gingerly will cause hiccups.

Maybe post some pics of your extractor from different angles? I'm having a difficult time understanding the "bevel" you're describing.
 
Sounds to me like the extractor is hitting the receiver ring and not allowing the bolt to close. I've seen this several times where the extractor rotates upwards when a round is stripped out of the mag causing the face of the extractor at the top, hit the receiver. On one example I had, all that was needed was a slight beveling of the top of the extractor and some polishing to make it work perfectly. Any time you have a mix master rifle the potential is there for stuff to not work 100%. Tolerance stacking, parts from different countries /models, etc. could all lead to a slight adjustment needed for proper operation.

Can you post some pics of the problem? That might help in diagnosing exactly what you are after.

What you're describing is what is happening to me. The extractor rotates up (left) and will not go into the machined groove in the receiver.

This one is actually an all matching original not a mixmaster but since the minor components are not serialized the extractor may very well be a replacement.

AAAAGGGGHHHH! Not again! There are probably a couple of dozen Threads and Posts here about this "Problem."

The Mauser and many other Military rifles are CONTROLLED FEEDING. They are intended to be fed FROM THE MAGAZINE, not by dropping a round into the chamber and closing the bolt. Many modern sporting rifles today will allow this, and people get the idea that any rifle will do it. As mentioned, it can and will break an extractor.

It can also be DANGEROUS. Slamming the bolt shut can push the cartridge forward, and collapse the shoulder. This creates EXCESSIVE HEADSPACE, by actually making the cartridge shorter and when fired, gasses can blow out a primer or the back of the case, allowing unpleasant results to the shooter.

It could also be that a previous owner forced rounds into the chamber this way. Check the bevel to see that it is not bent backwards toward the bolt and does not have enough clearance for the rim. Sometimes, the bevel is not factory original and has been ground or modified by someone who owned it before. If you have another similar Mauser that does work well, try substituting the extractors and see if the problem still occurs. That way, you can easily find out if the extractor is the culprit.

I absolutely know the difference between push round feed and controlled round feed. I am not trying to close the bolt over a round in the chamber, the problem occurs when feeding from the magazine. I will install an extractor from a K98 and see if it resolves the problem.

@ camster. The problem occurs just centimeters before the bolt is fully closed, the extractor rotates to the left (up) and hits the receiver rather than going into its groove.

It sounds like the rim/base of the cartridge is pushing the extractor up just before it chambers fully. Take the bolt out of the rifle and with a FIRED cartridge case, try to slip the rim upwards onto the bolt. If it moves the extractor, check the clearance and/or bent edge on the inside of the extractor. This can also happen if someone has dropped the bolt on a hard cement floor and bent the end of the extractor. Sometimes you find a small burr and a bit of light strokes with a fine file will take the burr off.
