Supersonic
Supersonic is a description of the speed of a bullet once it is fired, specifically speeds above 1,126 feet per second. This is the speed of sound, so anything traveling faster will break the sound barrier and create a sonic boom. Small arms do not create the sonic boom that a jet fighter would, but there is still a very loud and distinct “crack” as the bullet moves through the air at high speed. Supersonic ammunition is common and is usually not marketed as supersonic as many calibers and ammo types move this quickly of even faster by default.
