[QUOTE="load, post: 356300, member: 22789"] one of the problems is that air pressure builds behind the bullet during supersonic flight. when the bullet transitions from super to subsonic the air pressure from behind the bullet is released and causes the bullet to loose stability. there is no shock wave when transitioning from super to sub as there is in super sonic flight for a bullet to survive the transition it needs to have a shape that no air pressure can build behind of or of a shape that could handle the sudden high pressure release of air.......kindof like a football next problem how do you get a football shaped bullet to shoot well out of a gun?
