Those are both out of 20" barrels, I believe.
I have to disagree (not with that statement, though. I think the requirements of the War Department were just under the .30-06 in capability, however.). The .30-06 that the Garand used was downloaded from its maximum capability. Why? A kind of silly reason, really: The military ranges were to short. The range of the more powerful .30-06 was being used on ranges designed for the .30-03 and .30 Krag, and so they were overshooting past the range property. So, it is quite possible that the military .30-06 that was being used in 1951 was equivalent to the .308. However, a fully loaded .30-06 and a fully loaded .308 are significantly different cartridges in performance. And I vote on the higher performance for a classic rifle.Tell that to the war department. The 7.62x51mm round was DESIGNED to match the external ballistics of the .30-06 with standard 150gr ball.
