Having shot nra high power for years I learned early that there is an art to working a bolt action. In the rapids first 2 finger open bolt thumb closes it its a simple flick of the wrist, and on long actions a twist of the head for me. Trying to baby it or work slow will cause stickiness and or feed problems. My pre 64 match rifle threw brass farther in the rapids than my M14/M1A did.
A lot stoned a radius on the bottom corner of the extractor to allow it to snap over the rim when single loading. CRF wont jam up with a short stroke if the action. I also think it allows a more natural chambering of the cartridge with the fixed ejector.
Again it boils down to what you like, have confidence in, and feels right to you, Thats what really matters. Some of the newer actions with smaller ejection ports are almost impossible to singlle load or feed rounds in. A springfield, mauser, model 70 set up to load with strippers is pretty darned usable across the board.
