I wouldn't call 308win inherently accurate - BR case put that bar pretty freaking high. 308win needs quite a bit of work to be sub-MOA.
We'll have to disagree on this then. Of course the 308 cannot compete with a BR cartridge but we aren't talking about that either. The 308 is already well sorted out in terms of accurate loads and is not finicky with powder or primer selection. It is certainly not the ultimate paper puncher round, but its not hard to get great accuracy from either.
Don't take my word for it...straight out of the Sierra 5th edition reloading manual, "The 308 is an extremely easy cartridge to reload. Like the 222 Remington and 6mm PPC, the 308 is an extremely accurate cartridge. It is probably the most inherently accurate 30 caliber commercial cartridge ever produced."
