In 24" barrels, a common 165 ish gr hunting bullet, operating at SAAMI pressures in both .308 and '06...gives the '06 a hundred yard advantage, but 24" .308's are not common, so if you compare 22", then the '06 pulls ahead...would an animal know the difference? I don't know, but I don't have huge confidence whacking an excited elk at 200 yards with a 2100 fps impact velocity. Yeah, you can go with some new powders and push the envelope a little in the .308...but you are still trying to catch up to the obsolete '06. But, I admit a 1/2" longer action and bolt throw is a huge disadvantage...grin.
