You'reare right, of course, but they are out there. Training and practise are paramount importance. Coni Brooks comes to mind as one who can, who has used a .338 WM for deer hunting in Saskatchewan at least twice. Another women huntress in Barnes Loading manual used a .458WM for her elephant while several more used .270's through 7mm Rem Mags. That puts most tolerable recoil around the '06 level. In the right gun, it's not a kicker at all.
: Stock fit is most important. A friend I once had, now decesased, had an older '06 Savage that kicked harder tha my .375 does. It was horrific to shoot and was only an'06. Most 7mm Mags, I find kick about the same, same recoil for about the same performance. I much prefer the old Gov' .30/06 ctg. over about any 7mm for heavier game. I just revile in using my 7mm mauser for almost everything.
