I own a 7mm08 and hate it.. Not accurate in the gun i own. Recoil is just as stout or more than my 308 and ammo is about $10 more a box.
308 does it better!
Most people I know sell guns they hate. Why keep it?
And the difference between a .308 and a 7mm-08 is negligible, so saying either is superior to the other is ridiculous.
