Is this extractor broken?

This is from a Ruger M77 I just purchased.
I was test fitting some brass after sizing to make sure it will fit.

Brass fits fine…but pulling the bolt back does not pull out the case and “throw it” which is what happens when I test fit this brass in 2 other .308 rifles.

I’m thinking it’s got a corner broken off.
The corner closest to the plunger pin.

What’s your opinion and what’s the solution?

Edit- or is this model CRF which is why the extractor isn’t gripping the case?

Thank you in advance

does the brass come out of the chamber? If yes, it isn't the extractor. if it doesn't get ejected easily, then it's the ejector - which is the plunger. Put a drop of oil on the plunger and use a punch or something similar to compress it repeatedly. if it moves freely, then it should be good. if it is crunchy or hangs up, then the ejector should be removed, the hole cleaned and maybe you need a new ejector spring. Do not leave any oil on the bolt face after putting some oil on the ejector.
 
Thanks guys.

I took it apart and cleaned it up- it was filthy.

Works better now. You are right I think, it’s not broken.

What a pain in the nuts though to get the extractor to slip back over the retaining spring…there must be a tool for this?
Anyway it’s back together and working better.
 
"Tool" - I make one - read of it somewhere or other - not my idea - take some mechanic's wire - perhaps 3/4" (19 mm) length - use needle nose pliers and bend like a "U" or horse shoe shape - place onto BACK SIDE of the spring clips - use that pliers to pinch it shut - as you slide the extractor on from front, that will push the "tool" off - usually lost in junk on floor, so I make another one. Most bolts that have larger external extractor - like Mauser or Enfield - will have a specific place to install or remove the extractor. - you tend not to want to fight with the retaining groove at the same time you are installing the extractor..
 
WARNING! Somehow I snapped off the "ear" on a Ruger 77 spring clip - not the same as the military Mauser or Enfield for strength - so go "easy" on the Ruger 77 - maybe on all commercial guns?
 
OP - your initial post was wondering if that action is CRF or not - CRF means "controlled round feed" - either the magazine has the cartridge (controls it) or the bolt does - at no time is a CRF cartridge "pushed" forward by the bolt without the bolt gripping the cartridge, once the cartridge is out of the magazine - that is the "push feed" action. Unfortunately many people today think CRF means the large external extractor - a #4 Lee Enfield is CRF but does not have the large external extractor.

Somewhere I read that it was determined that some soldiers, under stress, would partially push the bolt forward - then yank it open - on a CRF action, that would eject a fireable cartridge if it was pushed forward out of the magazine far enough for the bolt to have the cartridge. But a subsequent forward movement of the bolt would pick up the next round from the magazine - with a "push feed", is probable that the first cartridge was partially into the chamber - the bolt did not control it yet - moving the bolt back might get the bolt face behind a second cartridge in the magazine - a forward motion of the bolt would have TWO cartridges trying to get into the chamber - usually referred to as a "jammed action".

I hunted with a push feed Winchester Model 70 XTR for several decades - I would be hard pressed to identify any particular advantage for a hunter for CRF versus "Push Feed". I do not recall ever hanging upside down from a tree branch by my knees, when hunting - and even then, I think my "push feed" would have operated properly. Usually a "push feed" has to be completely chambered and the bolt closed before the extractor has hold of the cartridge - not so with a CRF action - as soon as cartridge "pops up" from magazine, it should be controlled by the bolt - whether chambered and bolt closed or not. My Dad had a Model of 1917 Enfield - CRF action - I watched him unload the rifle, dozens of time - did not have to close the bolt to do so. Is perhaps the only significant improvement to the Mauser 98 design - as found on P14 and M1917 rifles - larger nose to the extractor - can be used as "push feed" for "one more" round, but are CRF, usually.
 
Some years ago, I had seen pictures of Phil Shoemaker's bear rifle - "Ole Ugly" - as I recall one of the best Mauser 98 CRF set-ups that I had ever seen. Perhaps 1/4" (6mm) of cartridge movement forward had the round "popped out" of the magazine and onto the bolt face - the cartridge rim was behind the extractor - I doubt much of the bullet had even entered the chamber at that point - the set-up then had the bolt drive that round into the chamber - no rattling or fussing to get in there - all controlled by the bolt face. About the best I had seen - what I have been trying to duplicate with my own guns. I suspect that is what a Mauser is supposed to do - would be very "slick" feeding.
