My understanding is that pretty much every place in Africa the 375h&h is the minimuim or they state the minimum in kilajoules of energy and I believe that the 375h&h also falls into the acceptable on that, but so do some of the really hot .30 and 338's.

From every one I've talked to the 375h&h is the absolute minimum for a stopping rifle , but pretty close to perfect for the client. Lots of pro's seem to use the old 375h&h for everything, but alot seem to prefer the over 40 and some over 45 as a stopping rifle.
