    en.wikipedia.org/wiki/Muzzle_velocity

    For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...

  8. Subsonic ammunition - Wikipedia

    en.wikipedia.org/wiki/Subsonic_ammunition

    Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr) bullets at velocities of 300 m/s (980 ft/s). For these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. Subsonic ammunition with normal bullet weights often fails to function ...
