(Disclaimer: I have no real experience with the Big 5 or Brown Bears so take this for what it's worth.)
I know the statement has been over used but it truly is the African .30/06. In the vast majority of the USA it's adequate for anything that walks. Even in those locations where it's light (Grizzly Country) let's not forget that it did in the largest Brown Bear ever shot at a range of 4 yards (less than 4 meters) which some estimates place at 2,500 lb.
I place the .375 H&H on the same plane. Not ideal for a 14,000 lb Elephant but adequate.
In fact I can't think of any single situation in the US where the .30/06 is my first choice but can not think of any where I see it as a major handicap.
The same could be said of the .375 H&H in Africa.

Early on, he did promote the .375 as an elk round, but that was still in the dawn of smokeless powder when darn little was available north of a 30-06 in this country (that hadn't been created as a BB round). Considering the quality of the soft points available at that time, a .375 likely was a better choice for taking a poke at an elk across a canyon. He subsequently was, of course instrumental in creating the .338 Win Mag. In Africa he loved to use his English doubles and used them extensively. He was willing to get in close or not take a shot. However, were he alive today, I doubt that he would advocate one as a first time African hunter's choice to take on safari - particularly the pure PG hunt which has now become somewhat the norm. I am sure he would still be part of the .40 + cal club for dangerous game. But I am equally sure his more articulate Nemesis O'Connor would be even more certain that the .375 was an ideal choice for a client's rifle.
