The longer I hunt, the less I'm convinced all this minutiae makes any difference.
Would happily hunt anything with a .308 that I've hunted with the .30-06--and these days I consider the .30-06 a "big" cartridge. Not like the .375 H&H or .416 Rigby, but even in Africa a bunch of Cape buffalo have been killed with the .30-06--or 7mm Remington Magnum, or .300 Winchester Magnum. Shoot any big game in the right place with a bullet that expands and penetrates sufficiently and they all die pretty quickly.
I haven't done as much hunting as you, but my thoughts are the same. The more I hunt, the more I realize that it really doesn't matter all that much from .270 - .300 magnum. A good bullet in the right place will handle most game. Heck, maybe even a 6.5 will do.
