fireman1291:
If your bullet is subsonic it will be silent, however, if it is suuper sonic it will make a loud drawn out crack. If you are in the butts pulling targets, when the bullet passes over head it makes a loud crack.
When I was shooting on several Marine Corps riflel teams, from the snapping in circle, about a half mile from the range, I could hear the bullets breaking the sound barrier form the muzzle to the butts.
