I have a Zastava standard length action opened up and rebarelled for .416 Rem Mag.
The extractor has a deep kink in the middle of the spring I guess to open it at the face to accept larger rim.
Feeds and extracts fast or slow no issues except it just looks wrong and I can't put enough pressure on it to get it over rim to get one on top of 3 down.
Anybody sell "tuned" extractors? Ship the bolt or entire rifle to someone to replace it?
Thanks, Scott

Nope; they have to be fitted individually to the system.
Meaning, each one is fitted to the rifle. Deep kink?
And if it doesn't ride over a cartridge in the chamber (a design feature of the Mauser, for Military use, is that all cartridges are fed from the magazine; single loading was not a tactical necessity as it was in the US and England's rifle designs. ) then the angle of the claw needs adjustment. Meaning, grinding. Now, if you found a factory mag extractor might work as is. But enlarging standard ones needs to be hand fitted.

There was recently a discussion about this subject under "Granite Mountain Arms G 33-40"

Kink or bend in the extractor is in the middle and looks like someone hit it with the edge of a hammer face and bent it in toward the bolt body.
It's deep and not a subtle bend.
Duane, searched through 4 pages of "granite arms" and didn't find it.

Scott,

The discussion Duane mentioned is in the Custom Rifle forum

That sounds like the bend put in Mauser 98 extractors to tension them to the bolt body. Sometimes you can press in on the extractor just behind the collar to assist snapping over a round in the chamber.

All or most, Mauser extractors have a milled step in the middle to make the rear portion thinner, providing the "springiness" that Bobster is referring to.
Are you sure you aren't looking at a normal extractor?

Nice caliber and rifle. I have a custom Zastava .416 RM full stock carbine (20" barrel) that was originally a .375 H&H Mag.

Zastava extractors all have that dimple near the middle, some more pronounced than others. My .458 WM Zastava is an example -

Just to be clear; it is not a kink or a bend; it is machined that way to do two things; allow room on the inside for the collar lugs, and to make the rear thinner to provide more springiness. The inside surface is flat; there is not a bend in the extractor. Also it needs room to clear the bolt guide rib on a 98.
If there is really a "kink" or bend in your extractor, then it has been deformed and might need replacement.
UPDATE; the above is for 99% of 98 Mauser extractors; looks like Zastava changed the design to eliminate the thinner rear portion, so they are flat all the way back, in and out.
