I agree.
There's also great high BC choices for reloading despite what many people think.

How heavy do you have to go in the .30's to get BC's like that? And there's no chance you'd get bullets heavy enough to match those BC's to the same velocity unless you move up to a .300 win mag or even bigger.
I consider .270 to be 'better' on paper than .30-06 because it will shoot bullets with comparable sectional densities faster and flatter than the 06 with equal if not better BC's. And depending on the load, will shoot bullets of equal weight (and higher SD's) almost as fast, if not as fast as the 06'
150 grain .30-06
SD .226
BC ~.435
Velocity ~2910 fps
150 grain .270 win
SD .279
BC ~up to .625
Velocity ~2830-3000 fps
If we compare bullet with comparable SD's
120 grain .270 win
SD .223
BC ~up to .460 (

Velocity- easily in excess of 3200fps.
The way I see it the .270 is measurably better on paper. Game wont likely know the difference, when they're hit in the same spot. (but IMO .270 is easier to shoot making accurate hits easier) but the .308 cal still has more choices for projectiles, much wider projectile weight selection for factory ammo, and longer barrel life.
