I generally agree. However, that damage, like the projectile and what launched it, can be proportional to the animal and still very lethal. Like
@Philip Glass, on almost any deer sized game I would much rather have a .30 inch hole going and .31 inch hole leaving from a tough heavy bullet through what matters than an explosive exit wound. Animals die just as quickly with a lot less destruction of meat or pelt. Such a bullet also causes significantly more tissue damage than any arrow (yes, I use to hunt fairly extensively with a bow).
I have used a 6.5 on a lot of European game in the form of 6.5x57 and 6.5x57R. The traditional heavy for caliber 154 gr loads in those drill pencil size entrance wounds and slightly larger than pencil size exit wounds on roe deer in Europe and whitetail in this country. The load is extremely lethal, and causes minimum destructive tissue damage to what does not matter.
Most recently in Zambia, I used my .275 with a traditional heavy for caliber 170 gr load for everything from bushbuck to a sable. That load, in this case Oryx, performs exactly the same.
What I find of zero interest to me, at least with respect to game, are fast light for caliber loads. They are needlessly destructive, too often do not exit, and have a far higher potential for not penetrating sufficiently. So yes, the Creedmoor can be a fine choice - with the right load.
