Mauser Extractor question.
11/16/2011 10:30:32 AM
Hey, Guys.
I have a nice Yugoslavian M48A in 8x57mm Mauser. (Shortened, Large Ring 98 variant, for all practical purposes).
It is in excellent condition, and very accurate, but I've noticed a very slight "glitch" in chambering a round.
What happens is that the bolt picks up the live cartridge from the magazine, but the case head doesn't pop up quite far enough to fully engage the bolt face, until the round is chambered deeply enough for a certain amount of "forced alignment" to pop it up the rest of the way up into the bolt face.
Close examination reveals that the very edge (end?) of the extractor claw is bottoming out in the extractor groove of the cartridge case head. The extractor eventually springs out slightly to pop over it when the bolt is shoved forward.
My concern is that I may be tweaking the bullet out of axial alignment with the case or even slightly bending the case itself when chambering aggressively from the magazine.
If I carefully removed some steel from the extractor to prevent it from bottoming in the case extractor groove, it would facilitate in-line alignment of the cartridge to the chamber at a much earlier phase in the feeding process, and smooth everything out.
(I THINK!)
Any thoughts or concerns I need to address, other than the obvious of being careful to not remove too much steel?

Well for starters I doubt you're doing anything to the ammunition that's causing any serious degree of degradation.
That said, go for it. It would be prudent to lock down a supplier that has spares in stock before hand

Yeah, it always goes BANG.
But it's just that I hate to take pains to handload precision ammo to minimal runout, etc, and then slam each cartridge bullet-first into the chamber wall at a weird angle. And it hangs up the cycling noticeably, diminishing the otherwise smooth feel of this fine firearm.
I reckon I'll just go ahead and do it, after all what's the worst that can happen?
