weak Argentine '09 extractor

[Calfed]

A few months back I glommed this '09 Argentine Mauser that has been converted to .308W. It is very passably accurate, but I'm having problems with the extractor. When I extract the case after firing, the case slips off the extractor after I've pulled the bolt back an inch or so. I then have to pick the case out by hand.

The extraction is easy, the extractor simply does not hold onto the case after an inch or so.

Is this because the extractor was designed for a different case or is the extractor likely just weak?

Thanks for any assistance.

You may end up doing what I had to do . . . .

Swap out the extractor for one that was used on a German-made M'98, in 8mm cal.

Works like a charm. --Jim

Another thought on your rifle . . . .

It may be that the other owner beveled the lower-front portion of the claw, in an effort to improve the feed from the magazine. . . .and went TOO far!

He may have improved, or smoothed up the magazine feed, but the extraction then suffered. --Jim

Someone ground the hook to allow for closing on a chambered ctg. Usually the mark of a novice gunsmith. There is nothing you can do except replace it.

Thanks, guys.

Bud, would the Brownell's extractor that you linked, which includes a 30.06 pre-fit model, work with a .308 case? I mean...is the 30.06 abd .308 case heads the same or similar?

Thanks.

I think that a "ground extractor" may be the trouble.

I've got several other '09 Argentines, including one that was drilled and tapped, but is still in 7.65 x 53 and has never had an issue with the extractor.

I took pics of the bolt face from the problem Argentine and the one that never gives me trouble....see if you can guess which one is from the .308W Argentine that the cases keep slipping from during extraction...

I'd say the one on the left. --Jim

Yep.

Anyone know if the extractors from Numerich or Sarco require any fitting?

Thanks

If you called them I'm sure they could tell you for sure but I would assume (probably wrong) that yes they would work just fine. I have in the past used large ring 98's to build .308 Win. rifles and used the original extractor and it worked fine. Of course I did the extractor test. They also make one that has to be fitted. I have accumulated several military 98 extractors over the years as spare parts but I also keep one new 98 extractor just in case. I assume (here we go again) you know how to check the extractor on a Mauser type rifle. There's nothing wrong with re-working a extractor to over ride the rim as long as you know what your doing, they work just fine when done right.

Some target shooters didn't want the brass thrown clear of the receiver, and just eased the bolt back, picked the case up from the action, and stuck them in the box. If the bolt was worked quickly it would still throw them out.

[Calfed]

You could be right about that, Johnny. I usually work the bolt slowly so as not to damage the brass by ejecting it onto the ground.

Bought a NOS extractor for a 7x57 1908 Brazilian Mauser from Sarco. It works much better
