"What will a 308 do that a 7mm-08 CAN'T do?"

Federal used to offer a High Energy .308 load with the 180-gr. Partition at 2740 fps at the muzzle; there was nothing in any load that the 7-08 could match with that. In all of my .308's, that load was very accurate and effective on game. Shame on them for quitting on it.
