79S,
I know more than one African PH who prefers his Cape buffalo clients to use 270-grain .375 TSX's rather than 300's, BECAUSE they tend to stop under the hide, while the 300's tend to exit. Buffalo usually live in herds, either a small herd with a few other bulls, or a bigger herd including cows and calves--and they're often in pretty thick cover, where not all of the other members of the herd can be seen. PH's prefer not to shoot two buffalo with one bullet.
Argumentum ad absurdum. There is nothing in North America close to Cape Buffalo in hardness and showing they are caught at that extreme end says nothing about the vast majority of use.
It also shows their tremendous respect for the penetration of the TSX. It is easily supported by empirical evidence that X bullets penetrate more. And not just a little more.
