Ballistically the 7-08 is hands down the better LR cartridge then the .308 Win. 2 reasons for this, one being the 7mm BC is hands down way better then .30 cal, and for two, smaller calibers with smaller bullets are usually faster, couple this with the better BC and it becomes easy to see why the 7-08 is better then the .308
Stick a 162g AMAX in that 7-08 and it spanks the 308 in every category...
Heck even the .260 with a 140g AMAX is better then the .308, maybe not in energy, but in drop and drift I know for a fact it is w/out even looking at the ballistic charts.
The .308 would be about the last cartridge I'd ever own...
