The push feed extractor doesn't hook the rim until the bolt is closed . CRF grabs hold of the cartridge as soon as it's picked up from the magazine as originally designed.
How do you have one in the chamber and a full magazine with a CRF bolt action?

Push feed was designed to hook the rim on bolt closing. It's a small tapered extractor unlike the large Mauser type extractor that was designed to hook the cartridge rim, and control the cartridge, as soon as the cartridge was picked up from the magazine.
Here's a close up of the Savage M99 as it picks up a cartridge from the magazine. CRF.

None of what you are posting is new to us. We understand how CRF works by the extractor engaging the round as it comes up from the magazine. The recent discussion has been about what happens when feeding a round directly into the chamber in a CRF action. Some work and some don't, depending on how the face of the extractor hook has been machined.
Properly ground CRF extractors, and some of them came from the factory done so, ride up over the cartridge rim to engage the hook into the extractor groove when closing on a round that enters the chamber ahead of the bolt. They still are CRF when a round comes up from the mag, while push feed never control the round until the extractor snaps (rides up) over the cartridge rim.
You are still ignoring the fact that ALL PUSH FEED bolts must have the extractor ride up over the cartridge rim to engage the hook into the extractor groove EVERY TIME they chamber a round, and do so without wearing down or burring the hook. Of course, because the extractor is steel, and the cartridge rim is brass. Again, think about this.

Ted, if you recall, the OP asked about his M98 and how to load an extra round after the mag is full. The M98 was designed not to ride over the case rim but to load into the mag and engage from the mag. . Grinding and beveling a CRF extractor was an after thought. Whether you press one into the mag or drop one in and force feed is the rifle owner's choice. . This is one reason I never lend my nice rifles but keep a loner one on hand for the occasion.
Yes, that was the original query. The discussion led to other posts as to how those Mausers could be successfully altered to work both ways, without compromising the reliability, safety, or utility of the action.

Out hunting and requiring a quick follow up shot then a drop in would be fine but to sit at the bench at the range and single load by dropping them in instead of pressing them down is something I don't do. . Like I said before folks can do what they like.
Meanwhile, three weeks after that... here we are. This is why space aliens lock the doors on their spaceships when they fly by earth and will never visit us.
A truly conniving gunsmith would not explain manipulating the bolt. Instead they'd say there's a problem with the bolt - but for a mere $50 or so, they could fix that dangerous defect for them!
Other lazy sods pay the gunsmith anyways so they don't have to bother with manipulating the extractor tang, just drop one in the hole, slam the bolt forward and go.

And, there is apparently a cohort without the brains or knowledge that their Grandfathers or Great grandfathers had, who are led to believe there is a "problem" with their Mauser 98, that needs to be "fixed". Likely the same who do not know how to inspect the guts of their bolt - yet every WWI soldier could do so in the dark, sitting in a muddy ditch, while it was raining, without using any tools except his fingers. But apparently requires an "expert" to do today, so not often actually done...

Never owned one but I doubt it's difficult. . I could be mistaken, as I'm not all that familar with Rugers, but I believe the Rugers M77 tang safety is not a true CRF.

The Owner's manual available on-line - page 6 - load from magazine or single load directly into chamber- made for that. Seems to be the same for later versions. My 77 Compact made in 2010 single feeds effortlessly - not a tang safety. As does my made-in-1955 Winchester Model 70. As does various P14 and M1917 that are here. Like my Husqvarnas and some Parker Hales built on commercial Mauser 98 will NOT. Neither with Swede 1896 nor the Swede M38. Very clear all the later can be modified to do so, but not built that way when new.
When loading directly into chamber, you are using that big hooked claw extractor, but are "push feeding". You get "Controlled Round Feeding" when same rifle being fed from its magazine.
