RE: 308 or 243?
there is a wide variety of factory ammo available for the 7mm-08. hornady lists 3 different 139gr loads. winchester lists 2 different 140 gr loads. remington lists 1 120 gr load and 3 140 gr loads. and federal ammo lists 1 150 gr load and 4 140 gr loads. that's 14 different factory loads......that number is exponentially higher if you reload.
