Huh, the 7mm 08 superior to the 308? Best load here is 178gr eldx at ~2700 fps w/ 308 compare to 7mm-08, 150gr eldx at ~2790. 308 drop is 45 inches at 500 versus 7mm 08 drop of 42.
If you want to compare apples w/ apples, the 308 pushes 150 gr bullets at a higher MV of between ~2850-2900 fps. More energy at a higher muzzle velocity, drop is 44" with a even a lower BC bullet. Clearly superior? I think not...plus I value the better 30 cal availability of bullets over 7mm (at least in a couple of areas I have lived in).
