Slightly less, possibly; flinchingly-less-than perfect: not so much
I suspect the 33s might be some of the worst, actually, since they approach 375 power levels in 7 mag-weight rifles. (I don't know anyone who actually appreciates the 375s in standard/magnum weight rifles either though either.)
My .338 Ruger is nowhere near a "7 mag weight rifle". It outweighs my sons Ruger 7 mag by a pound or two. And they're both walnut 77 Mark II's.
