Win M70 ejector adjustment (CRF-models)

[Somnas]

Hi there,

I got my first magnum rifle last year, a Winchester Super Express in .375 H&H, which is also my first Winchester. Great rifle.

The only thing that's bothering me is that if I cycle the action properly the brass gets ejected so violently that the case necks get deformed against the rear of the receiver.

My guess is it's possible to adjust this behavior by trimming the fixed ejector a little bit, but I wanted to see if anyone got any pointers before I try it myself.

Also, a quick thank you to the members of this forum. I went through a lot of both old and new threads before deciding to buy this rifle and I'm really pleased with it.

In my opinion, I would leave it alone as you’ve already noted, The force of the ejection is related to how fast and hard you cycle the bolt.

If you’re wanting to protect your brass for reloading, then don’t cycle the bolt as hard… but in a Hunting situation, I would rather have it clear my brass.

CBeck is spot on, don't mess with it. I have the same Winchester CRF model 70 as you. My rifle ejects to same way. Cycle it fast and hard, the brass gets deformed. If you cycle it all limp wristed and soft, your cases won't deform. You'll be just fine reloading that brass.

That's generally the way these rifles are. I have experienced the same thing with my Mausers and Remington 30 Express (US1917). The dents are no issue, resizing die takes care of that. I agree with above, don't mess with it.

Thanks, I know the sizing die will take care of that particular example. Others are more mangled and will need some care before sizing. And yes, of course you want reliable ejection and feeding.

My issue is that this is beyond what’s needed for reliable ejection and like nothing I’ve seen on my other m98 rifles.

It’s giving me other headaches as well like losing cases after they’re sent flying 20ft or more into the vegetation while running drills on the range, but the point was not to argue it’s function but to learn if someone has experience adjusting the ejector.

Seriously suggest to not alter the extractor.
That series of Model 70 Winchester, and I have owned a few, have poor quality spring steel extractors, and if bent to modify, lose the proper tension to reliably extract a case. I have had a M70 .375H&H fail to extract a case tight in the chamber.

An article in Rifle magazine by John Barsness, quotes D'Arcy Echols, a renowned rifle maker regarding this improper heat treatment of M70 extractors.

I replaced the extractor with a Williams Firearms spring steel extractor, problem solved. I do not think Willaims Firearms are making this part now, as current FN/ Portugal extractors are properly tensioned spring steel.

Proper Mauser 98 extractors are tensioned spring steel.

Perhaps order a current replacement extractor, and have it fitted by a qualified gunsmith.
