So does any cartridge shooting a given 30 caliber bullet faster (if that's your definitation of "dominates") than a .308 does.
The .30-.50BMG (below, with 5.56 NATO round for comparison) dominates them all and dwarfs the .30-06 Ackley, now, doesn't it?
How 'bout a .30-40 Bofors; a 40mm Bofors heavy AA machine gun round necked down to 30 caliber shooting 1000 grain 6 inch long bullets? You could use three kernels of powder used for 16" battleship guns; they're about the size of .410 gauge revolver cylinders. Would be the most overbore cartridge in history. But very efficient; it would only use 3 kernels of powder compared to about a thousand or more in a .308 case.
OK, your turn in this (about to get stupid "mine's bigger than yours") issue.
