I have no personal experience with it, but have talked pretty expensively with one of the guys who worked on getting it adopted as a potential US Military round (he is located in Houston, and his site is http://www.competitionshootingsports.com/).
Cartridge length is teh same as the .223 recoil about the same, but ballistics that exceed the standard .308 with 175 GMM Match ammo at 1,000 yards. I know some benchresters have picked up on it, as have some of the Highpower rifle guys.
