while you don,t need the power a 375H&H potentially provides, it works just fine!
Ive been hunting ELK and mule deer, for 35 years in several western states, colorado,wyoming, oregon, calif. and idaho, mostly my back-up rifle on many elk hunts is a sako 375 H&H manlicher carbine, the load I normally use is a hornady 270 grain spitser over 80 grains of winchester 760
while I tend to hunt far more with my 340 weatherby and 250 grain spitzers the results on game are not distinguishable, both punch thru from any angle and then exit, most shots drop game instantly, and with less meat dammage then I comonly see from the guys useing the faster light caliber mags like the 7 rem mags
youll have guys give you a bunch of B.S. over carrying a 375H&H occationally, but I doubt youll find anyone dumb enought to even imply it won,t drop elk like THORs HAMMER! if YOU place your shots correctly!
now since I rarely get shots over 300 yards and the average is more than likely closer to 150 yards I doubt that theres much a 375H&H won,t do that the other less powerfull rifles can. but the one thing I have noticed was that the 375 H&H seldom has problems with bullets shreading on impact or failing to exit, (COMON PROBLEMS with some of the smaller high velocity rifles)
I could easily spend the rest of my life hunting with just a few rifle calibers and a 375 H&H would be high on the list!
but Id say theres (20) 7mm mags and (30 )30-06s out there for every 375 H&H youll see in use
