Mauser 98 - to push feed Q.

[ELR LVR]

I am not much of a Mauser guru other than owning a Ruger M77
So for fun I aquired an old Mauser 98 and to state first off
am aware
They are "Designed" to be fed from the magazine
Regardless I want to be able to single feed load it then close the bolt.
I have researched and read the old wives tale of single feeding a Mauser being damaging to the extractor is false, Baloney, BS and many guys have done it with no issues for years.
I tend to swing that direction considering the extracor is springy for - A REASON
This is the issue - when chambering a round the extractor even though ramped will not skip over the rim of the case
With the bolt out of the action---
And - With the extractor in the "Open Bolt" position, if I push a case head againast the boltface I notice it has enough springiness to open up enough to easily skip of the rim of the case.
Yet if I try to close the bolt on a loaded round, the bolt will not close since the extractor is not being allowed to skip over the rim, something is preventing this.
------------------
So I am wondering if the clearance between the extractor and the action is not allowing
the extractor to spring away from the bolt
And my first thought is to grind away the outside of the extractor edge to allow more clearance for it to move enough.
Shown are a few pics and one of where it shows some rubbing against the inside rail of the action where I believe grinding away to clearance may help or even solve what I want it to do
-----------------
I also pose 2 more questions:
1. Why have the whole extractor be springy enough to move over the rim when open
---yet not spring over the case rim in closing?
2. If I clearance the outside of the extractor, would it then be prone to slip off the rim when trying to extract a case?
Thanks

When I single feed a round, I just push it down into the magazine.

You are asking the extractor to do something it's not designed to do.

I have read people do that too
But "can" it be fed on top of the magazine?
Again I pose - Why is the extractor springy if it never gets sprung ?

I understand what you're suggesting
However,
Why is the rim of the extractor ramped then?
Almost - I dunno, as if someone had in mind for it to slip over something?

Talk to Gmac on this board, he grinds a corner off of the extractor and it will single feed without picking up from the magazine. This was a very common modification in the 50s and 60s when many were sporterized.

I don't have a Mauser but do have a Clackamas Kimber Model 84 with controlled feed. I sure as heck ain't going to do any grinding on it.

I don't own a single rifle that I wouldn't modify to suit my needs.
I understand not wanting to modify a collectors item like an early Model 84(I got to handle one of them once!).

Yeah well, being a machinist , engineer etc
I've done things like make unobtainable gun parts by hand with a file
adapted transmissions into things that would not accomodate a different transmission
building my own custom long range rifles that are repeatable past 1 mile
But I also live by this creed I adopted when i got into my Gold Mining Phase
Explore where others have already found Gold first
--------------------------------------------------------
Same here, when I am in new territory, I explore what others have tried first.
I feel pretty confident I can modify an extractor, being just the tip of the iceberg

It's ramped so that it fits the cartridge extractor groove and it also allows the case to be ejected easily as it can pivot on the thin edge of the extractor. If you think it's not necessary to be shaped this way, take an extractor made for the standard case head (.308 size), grind it down to the size of a magnum extractor and leave the edge full thickness -- rather than beveling it. Won't work very well for feeding or extraction/ejection.

Copy, thank you, makes sense
So I have narrowed down to the fact that yes, as the extractor springs outward to try and slip over the rim
the outside edge of the extractor body is hitting the inside of the action.
I believe I am going to leave it, knowing that should I get a difficult to extract case
It will not spring outward and slip over the rim if I have to beat on it a little bit
Ensuring positive extraction
For a hunting gun that is more important
--------------------------------
Even though this action will be for a hunting gun, I wanted to explore the possibilities
I mean cmon guys, ya really got to get over this whole
"Gotta leave it stock" attitude as if its a '65 mustang fastback
You gents never welded up your 1911 barrel hood for more positive fit, or the lowers lugs for
improved lockup and things like that?
(leave it stock, that's the way it was designed from the factory, doesn't mean it cannot be improved or perfected)

I push case rim slightly into magazine box and extractor jumps over case rim.its always worked for me.
You can do it by feel without head up looking after awhile.just push rim below feed lips

.....grind away.

yeah thanks, I will, once its all back together
Except while the barrel was in the lathe right now and I was checking headspace
Throating the bore, checking freebore on the bullets I want to use etc etc
By muscle memory I kept inserting the case in the chamber and trying to close the bolt
and by hand had to keep fitting the case into the extractor etc etc
Not being used to a Mauser, it was ticking me off
And when something that is inanimate ticks me off
it either gets modified or sold off
So
While its all apart I thought I would explore the possibilities

I have several mausers and I can drop a round into the chamber and close the bolt on all of them. So grind away carefully. I can magazine feed just fine also.

Excellent, now we're gettin somewhere with someone who understands...
Most people own and most importantly "USE" our guns because of what they do,
because of how they perform
Not because of how "original" they may be, that is not why I buy any gun.
a guns value means nothing to me if I never intend to sell it
unless maybe.... its a $200,000.00 Purdey Shotgun

Compare the extractor from an FN single shot Mauser to a standard 98 extractor. The single shot doesn’t have a magazine. It’s a push feed Mauser. I’ll try to get a side by side photo tomorrow.

You beat me to it!

I have 5 Mausers in the rack. All of them will allow single feeding because I altered them so they would. One is my primary hunting rifle and has been used every year for the last 45 years. Mauser designed the system to prevent double feeding (by preventing any feeding other than from the magazine). There may be some value to this but it's hard to see. You will note, both the Springfield and Enfield rifles, though designed as CRF actions, also allow single loading. Modify the extractor as necessary. Be careful and don't remove too much material. in any location. The extractor should just be able to hold the cartridge in the bolt face without dropping it. WH

I have had a number of the FN single shot actions and still have a couple. The bevel on the extractor is longer (by changing the angle slightly), so that the head of the case does not hit a flat place on the front of the extractor. It hits the beveled area instead, forcing the extractor outward so it can slip over the case head. It does mark up the rims somewhat, particularly on the .222 size case heads. The outside corner of the extractor is also reduced in size a little, although there appears to be enough clearance in the receiver for it to spring out without that corner being cut down any -- but a military receiver might be different.
