Yeah, the 6,5 Creedmoor will do things the 6.5x55 won't. First, the cartridges fit in a 2.8" magazine. Second, they're short enough, with a long enough neck, to allow flexibility in seating long 140-grain match bullets.
Those are the two reasons it was developed, not to replace the 6.5x55. Apparently that's a difficult concept for many shooters to grasp.
