Ditto what Dave said. The Mauser (CRF) action is considered superior by some due to the controlled feed and stronger extraction. As a result, it has often been preferred for dangerous game animals(reliability). The "push feed" does not control the round going into the chamber and arguably has less reliable extraction, but encloses the case head completely with resultantly more support - and thought by some to be more accurate. I think that purists can make a case for either side.
I have several rifles of each type, and I have never had a reason to criticize or really prefer either action. I have worked my bolt as fast as I can shooting at running game with a push feed and never missed a lick, and my CRF/Mauser type rifles shoot as accurate as any of my others. I am not a bench rest champion shooter, but a hunter. In my experience, there has been no practical difference. I have had excellent results with both. BTW, I have a 77 RSI in .308 and I really like it as well.
