"Split the difference"& get a 7mm-08! Flatness of a 270 + much increased utility, doesn't require long actions nor long barrels for max velocity which equates to lighter & easier handling. MUCH greater bullet choices for reload/custom ammo in a 7mm vs a 270. Plus, as accurate as the 308 is, the 7-08 is typically even more accurate!

As for elk & larger game, I can't imagine ANYTHING a 7-08 with 150grn mono & prem bullets can't do that the 270 with 150 mono/prems can!!!
