I should have read the whole post before responding ".50 caliber machine gun
bullet." The first man-made object to break the sound barrier would
probably be either a round ball from a muzzle loading rifle...
That one's sure enough, as we're only looking at somethng like 1070 fps, plus or minus a bit.
Easy for the smaller calibers.
