I think the whole CRF argument is just utter nonsense.
Think as you wish, but the facts differ ... celebrity choices notwithstanding.
Winchester, CZ, and many other rifle makers bask in the sun of CRF! The new Winchester could have went either way; CRF was the choice, and the favorite of millions of riflemen in the USA for a long, long, time. It is a superior design for folks who may actually need a rifle to defend life & limb. Push feed is wonderful for animals that don't bite back.
To argue otherwise is just utter nonsense...
Selby's legacy is his legendary use of his 416 Rigby on dangerous game. Call Rigby and order a push feed ... let me know how that goes...
When I use to check my bear baits in Colorado, I had a push feed .338 Winchester, my Remington Custom Shop KS 350 mag, and my Winchester 7mm STW, and my Weatherby 300 Mag ... all lovely rifles that took more game than I can list, but, and there always is a but in life, I took my O3A3 Springfield ought-six because I trusted the CRF action when possible close work with bears was the job at hand!
I also shot thousands and thousands of rounds through my push feed Remington 10x in .220 Swift, which was great on prairie dogs, but, and there always is a but in life, if it were rabid coyotes that I was chasing I would have taken my O3A3 with accelerators instead ... for the same reason!
Danger: CRF over Push Feed any day of the week.
Push Feed was born to cut the costs for the rifle makers ... Period!
