Far too much is made out of different calibres, of about the same class. Jack O'Connor stressed using a proper bullet for the game hunted. That said, he said one could spend a lifetime of hunting without seeing a difference between the 270 and the 30-06.
He also stated how many hundreds of big game animals he had either shot, or seen shot, with each of the 7 x 57 Mauser and the 7MM Remington Magnum. He stated he really couldn't see any difference between the two in killing power. Good hit, dead animal, poor hit, wounded animal.
As a point of interest, he also once stated that the almost universal, 170 grain soft point bullet in common 30-30 ammunition, was a perfect match for the 30-30 rifle. He said the 30-30 with those bullets performed beyond what one would expect, from just looking at the ballistics of it.
