Supersonic vs. Subsonic Ammo: Hear the Difference in Sound
This video compares the acoustic differences between supersonic and subsonic ammunition. It features live fire tests at 100 yards using a .223 caliber round in an AR-15 and a .38 Special revolver. The demonstration highlights how the bullet's sonic crack can arrive before the gunshot sound with supersonic rounds (AR-15), while subsonic rounds (.38 Special) produce the gunshot sound first. The tests are conducted safely and are aimed directly at the camera.
