This is mainly a quasi survey for U.S. hunters, but how many CRF actioned rifles have you seen while hunting? In thirty plus years of hunting in Colorado and Wyoming, I've seen one (unless the Ruger M77 counts as semi?) after observing and talking to many, many other hunters. Just interesting.
Why would the Ruger 77 be considered semi CRF?
I own five Ruger rifles, 9.3x62, .300 Win Mag, .375 HH, .404J, and .416 Rigby. I consider all of them CRF, but have been told they are not "true" CRFs. So I don't know why they are not.
Don’t really know, I’ve never owned one, except my M77 in .220 Swift? But, from what some of the M77 experts have said here, is the Ruger RSMs are CRF and the others are not? Don’t know for sure?
Confusing the Mauser external claw extractor with CRF...
The title says it all: many confuse the Mauser external claw extractor with controlled round feeding. This is erroneous.
The only test of CRF is: does the bolt carry the round into the chamber? If the answer is yes, this is a CRF bolt. If this answer is no, this is a PF bolt.
The extractor type as nothing to do with CRF. I am tempted to add: period.
For example, here is the bolt of a Steyr Mannlicher Luxus, circa 1970's. As can be plainly seen, the bolt carries the cartridge, but it doe not have a Mauser-type external claw extractor. This is a CRF bolt.

The 3 telltale signs of a CRF bolt are:
- It has a cut-out at the bottom of the bolt head in order to allow the cartridge to slide under the extractor as the cartridge comes out of the magazine;
- It has an extractor wide enough and tensioned enough to secure and hold the cartridge as it comes out of the magazine, and CARRIES it into the chamber;
- It does not have a spring-loaded ejector plunger protuberating from the bolt that would prevent the cartridge from sliding under the extractor, and that would prevent the extractor from holding the cartridge.

Ruger 77 Mk1 "pretend CRF"...
The first generation of Ruger 77 had a Mauser-type external claw extractor, but they did not have the cut out. As a consequence the bolt did not grab the cartridge from the magazine and did not carry it into the chamber, it pushed it ahead of the claw extractor that jumped the rim of the cartridge when the bolt was closed. This was a "pretend CRF" but actually a PF.
Just like, to this day, the Ruger 3 position safety is a "pretend bolt-mounted, firing pin-blocking safety". It is located on the side, like a Win 70 safety is, and it is made to look like one, but it is not actually mounted on the bolt and it does not actually block the firing pin. It is mounted on the action and blocks the sear, a much less reliable option where a firing pin cocking piece can possibly jump the blocked sear in a hard fall...
Non-Mauser CRF rifles...
A number of well known rifles do not have the Mauser-type external claw extractor but are true CRF: Mannlicher Schoenauer, Steyr Mannlicher Luxus of the 1970's generation, Sako 85, etc.

CRF function has nothing to do with extraction...
The bottom line is that CRF function has nothing to do with extraction. Its purpose is to prevent double feeding and/or pushing inadvertently a cartridge into the chamber that would stay in the chamber when the bolt is retracted without being closed.
I have converted instantly a number of friends from Rem 700 to Win 70 by demonstrating side by side the Rem 700 PF leaving a cartridge in the chamber and the Win 70 CRF pulling it out. This is a safety issue not an extraction issue. This does not mean that these Rem 700 owners rushed to buy a Win 70, but it means they understood instantly and recognized the superiority of CRF
from a safety point of view.
The confusion comes from the fact that the Mauser 98 introduced simultaneously the claw extractor (extraction function) and CRF bolt (feeding function) and many folks merged the two concepts into one in their mind, but this is not the case factually...
