.... Penetration given the same bullet is caused by how much velocity it strikes the target with...
This rather robust study does not agree with that statement. Not entirely intuitive, to me anyway, but the study showed that very high velocity does not increase penetration. It doesn’t hurt with “premium bullets”, but definitely does not help with standard lead core bullets.
Interestingly, the only TTSX bullet I’ve caught from my 338 Fed was a ~35 yd shot with a muzzle velocity of 3050. A PH I hunted with made the statement that for the relatively short ranges they typically see, a heavy bullet shot at 2400-2500 tends to work the best.
