There are a lot of misconceptions about CRF. They don't
FEED any more reliable than PF rifles. Upside down or from any other position. The CRF advantage much more reliable extraction and ejection. Especially if the rifle is filthy. Under "normal" conditions most of us will never notice the difference. A PF rifle in pristine condition will function just as well.
I have both types. But if I'm hunting in a remote wilderness setting, possibly in harsh weather conditions, where the rifle could be dropped in mud, sand, snow, etc., I trust a CRF rifle to function much more than a PF rifle. If deer hunting, and my rifle fails to extract and eject I may lose a trophy at worst. But if hunting something that bites back I could lose my life. Either way, the harsher the conditions, the more I want CRF.
Years ago hunters went on weeks, or even months on long expeditions into wilderness areas. Today most of us spend a day in the woods and are never far from home and proper tools to disassemble and clean a rifle. CRF meant a lot more to the guy on a 2 week horseback hunt in Alaska or Canadian wilderness.
the crf rifles of today are not truly crf.
I'm gonna disagree. The early Ruger 77's with the tang safety had the large claw extractor, but the plunger ejector from a PF rifle. Those rifles did not allow the extractor to snap over the rim until the cartridge was completely in the chamber and the bolt closed Those were not CRF.
But the 77MK-II, Hawkeye, Winchester 70, and all of the older guns that have had the extractor modified to load straight into the chamber are still CRF. I've owned at least a dozen Rugers, Winchesters, MK-X's, and Kimbers with CRF actions. Every single one of them had the cartridge rim under the extractor with less than 1/8" of forward bolt movement. It's not like the old Rugers, or other PF rifles that didn't get the rim under the extractor until the bolt was closed.
And despite the Controlled Round Feed name, feeding the cartridge into the chamber was never the real advantage. It was always the extracting and ejection. The newer designs may need a tiny fraction of an inch more bolt movement to get the cartridge rim under the extractor, but that doesn't detract at all from the real advantage.
