I just finished rereading the 5.45x39 section in Emergency War Surgery, which says that the M74 bullet has onset of yaw at 7cm (~3"). That's rather longer than I thought it was when looking at the wound profile drawing.
Perhaps very early, ideal (1") yaw just cannot be achieved with a long, streamlined projectile?
