Lee, the key to RF actions is the same as CF. If it holds the barrel on it will work. Just as in CF BR the real key is what happens while you are swaging a bullet under heat and pressure down the barrel. I'd defy you to dermonstrate why a Reming, Hall, Bat, Panda, Hart, Niseka, or any other CF action is better. RF is the same. A Rem 40X, Time, Anschutz, Turbo, 10X, Stiller, Swindlehurst, etc. will all shoot, just depends on what you like. I don't think there is any advantage to 6:00, 12:00 pins, 1 lug, 2 lug, 3 lug, 4 lug, left port, top port, right port, etx. I've tried or worked on all of them and it makes no difference that I can see in how they shoot, only in what shooters like in terms of looks loading, and gun handling.
It's all barrel/bullet/ and shooter dependent.
