Unfortunately you’re illustrating what you don’t understand rather than what you do.
At 2200fps and above, as the FBI ballistics lab found long after the worlds’ militaries, the waves travelling through tissue rupture cell walls and cause radiating tissue damage. This is why they abandoned 9mm MP5s in favour of 5.56 carbines. This effect is the ‘jello’ lungs and tissue you’ll see with a high velocity impact. The faster the bullet is going when it hits, the more of that occurs and the further from the impact site it carries the effect. Below 2200fps impacts, the effect abruptly switches off and the cell walls hold together except in the immediate vicinity of the impact.
They also found statistically, unarmoured low velocity impacts to the torso were fatal in 1 out of 3 incidents with immediate medical attention, where high velocity impacts were survivable in 1 out of 3. A .45-70 punches through the animal typically, causing little tissue damage and sending the energy it has largely out the other side. This doesn’t make for an impressive kill, though it is lethal. A .270, hard as it is to rationalize does more work inside the animals, and more damage than a .45-70. The least impressive round I guided on big bears was .450 Marlin.
If you speed a .458 bullet up to 2400-2500fps at the muzzle, it becomes very impressive at short ranges where it arrives above 2200fps. Few want to tolerate that recoil on this continent. As for going off the continent and your Africa comment, there’s only a small handful of species that require .375 and there are few here who hunt them, and it applies to none of our species on this continent less perhaps wood bison. Excess penetration is just wasted on things like Grizzlies. And let’s be clear, a .45-70 and a .375 H&H aren’t comparable in effect either.
