I've heard that more and more snipers are going with the .300 win mag short, at least vs. the .308.

I left the military 12 years ago. They did a heck of a job with the 308. I don't see anything magic about the round though, they used a bolt action. With a bolt action, you could choose about any caliber you want without the issues of developing a semiauto action for an extralong cartridge.
