The Creedmor doesn't do anything that a 260, a 6.5x47 lapua, or a 6.5x55 doesn't already do. It's just so stylish to introduce a proprietary cartridge right now. And I think most people buy a 6.5 because they're tired of lobbing in 308s, not because they're Fudds looking for an 8000 round barrel life. It doesn't bother the long range guys I know a bit to replace a barrel at 3-4000 rounds.
Build it on a Savage, and when you shoot the barrel out (which I dream of!), you spend $300 on a new match barrel, and put it on yourself in 30 minutes, in the garage.
