My Dad (1922-2004) hunted in Wyoming for elk nearly every year until we moved east to Pennsylvania. He toppled well over 20 elk with his 300 Savage levergun which is ballistically similar to .308 or 30-06 out to about 200 yards. Beyond this distance the larger cased cartridges have the velocity and energy advantage. But to further illustrate this power, 300 Savage has about the same energy at 200 yards as 30-30 does at 100 yards.
My elk rifle is similar to Dad's except for .308 chambering. None got away; they all were downed humanly.
