With hunting most North American game, (big bears being the exception) the concern is less about being charged of course, but of a rifle getting jammed up in the excitement of one's trophy of a lifetime getting away after a wounding or clear miss shot. Those who say they never have done either are only proving that they have not hunted very much yet. One thing I admire about Craig Boddingtons writings is that he often admitted his missed or wounding hits, talked about how they happened, and what he changed, if anything, to try to be better in the future. Boddington has taken more game than most of us will ever even lay eyes on in our entire life and at ranges near and far.
And even if one does not really NEED a CRF, fixed ejector, claw extractor, mechanically advantaged extraction as the heart and soul of one's rifle, we do not really NEED a lot of the things we insist on when it comes to out gear. Why NOT start out with the better action as the heart of an expensive build?
On that topic, there have been hunters in the recent past and perhaps still living who have taken FAR more game than any of us ever will carrying nothing more advanced that a Savage model 99 in 300 Savage with a Stith, 7/8ths inch tube, 3x scope. Need has little to do with what we wealthier American hunters choose and prefer to hunt with.
The pure raw accuracy potential being equal, I can think of no reason why one would not choose to start with the better, in may ways, action. When I begin a build, I much prefer to make each component the very best I can get. Since there is zero reason not to start with a Model 70 or nicely tuned Mauser, why not?
My .02, hunt with what you like and have fun!
