40+ years ago this discussion would have smelled of the Elmer Keith/Jack O'Connor conflict of big bore/heavy bullets vs small bore/high velocity,Elmer pontificating about 6 270-wounded bulls for every one brought to bag...
We are smarter today and have better bullets;those from the 270 Weatherby will skewer an elk up close without blowing to smithereens,and still reach across canyon when needed....and items like the 250 gr TTSX from the 375 make 400 yard shots as easy as with a 270 or 30/06,from a trajectory standpoint...no need for lumbering round nosed stuff in the 375 as far as elk are concerned.
Either one is going to work and not much need for a lot of worry about which one to take.
