The 260 has 2-3 grains more capacity and the 6.5x55 around five but I see loads for the Creedmoor that are faster than either. Is this due to the mythical cartridge efficiency or over optimistic reloading? According to JBs one quarter rule the 260 & 6.5x55 should get at least 30 to 60 fps more than the Creedmoor.
It doesn't out run them, but 30 to 60 FPS means diddly squat.
