Well, anytime you cross the barrier, the sound waves compress into the boom up or down. If your going faster, all the sound waves are behind and if your going slower, some are behind and some are in front. Just at that magic speed, all the sound waves are in one place. If that makes sense.
And everytime you cross you, it creates pressure around the object. Hense the reason they say a F16 flying at 100ft will break out windows if it crosses it or knock a man down.
So I would imagine this destabilizes the bullet?
