These comparisons are usually brought up at 1000 yards where the tiny cased 223 has a major disadvantage in starting the long bullet fast enough out of the barrel to maintain enough speed for stability out at that distance. Stability is the factor here not the BC. As speed drops the bullet starts to destabilize in the 223.
