Since I'm still looking for the load it loves, I have shot my Model 70 XTR in .338 Win. Mag a good bit lately off the bench. 5-shot groups. It can be a bit to handle with full-power loads, but you've gotta concentrate on the sight picture, breathing, and trigger squeeze. Yeah, it whaps me pretty good. I use the "free recoil" style.
The worst beating I ever took was with my buddy's .375 H&H in an Encore. Like was said before, that thing actually gave me a headache!! Of course the 'scope eye" I got after the first shot probably didn't help either....
