The only thing a 308 brings to the table is cheaper factory ammo. That's about it's only redeeming quality. The 243, 260, and 7-08 are all a better use of that case.
Better how exactly? I own all four and find nothing wrong with the 308.
What can the other three do that a 200 grain partition going 2400 fps can't? My favorite of course is the 7-08.
