[QUOTE="4ked Horn, post: 69309, member: 11"] We all seem to know how much I love supersonic bullets. [img]/ubbthreads/images/graemlins/wink.gif[/img] During the time the bullet is supersonic the shock wave coming off the bullets point will cause an area of reduced air density near a bullet body ( which is why a boat tail gives very little benefit to bullets in SS flight) so the drag of the rifling groves would still be quite small (nearly 0) untill the [i]fairy dust[/i] was all blown away and the bullet came back from the "spirit world" and flew subsonic again.
