Specific reductions depend on the ammunition and suppressor. Main article: Suppressor § Subsonic ammunition and reduced sonic signatureĬombined with firearm sound suppressors, subsonic ammunition may significantly reduce sound levels compared to normal ammunition. These are designed from the start as dedicated subsonic projectile systems. 45 ACP ammunition load, of a 230 grain bullet at 850 feet per second, is naturally subsonic.Īlternatively, specialized firearms and ammunition may be used to optimize total subsonic ammunition effectiveness. For example, the traditional American military standard. Some ammunition types were inherently designed with heavier, slower standard bullet weights and velocities. Subsonic ammunition with normal bullet weights often fails to properly function in such firearms. Subsonic loads for 9mm commonly use 9.5 grams (147 gr) bullets at velocities of 300 metres per second (980 ft/s).įor these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound.Īs an example, the very common 9×19mm Parabellum standard military round is a 7.5 grams (116 gr) bullet at velocities typically around 360 metres per second (1,200 ft/s). Standard calibers Subsonic versions of standard rounds Some subsonic ammunition is used in non-suppressed firearms to gain the advantages of heavier bullet weights. Subsonic ammunition usually uses heavier bullets to retain as much energy as possible at the lower velocities. This avoids the supersonic shockwave or "crack" of a supersonic bullet, which, particularly for suppressed firearms, influences the loudness of the shot. ![]() ![]() Subsonic ammunitions are ammunitions designed to operate at velocities below the speed of sound, which at standard conditions is 340.29 m/s (1,116.4 ft/s) or Mach 1. You may experience cycling issues when used with compact and subcompact handguns.Ammunition designed to operate at velocities below the speed of sound *This product was developed to function in full size 9mm handguns and roller lock subguns. Freedom Munition’s HUSH does not have to be fired through a suppressed firearm and will function in non-suppressed firearms. HUSH Subsonic ammunition doesn't exhibit a supersonic crack thereby making HUSH ammunition quieter when shot through your favorite suppressor. Subsonic loads are ideal for shooting through suppressors because they help reduce the sound signature better than standard ammunition. The bullets and their profiles were chosen to give each load the most consistent, accurate performance of any available suppressor specific ammunition on the market. The ballisticians at Freedom Munition’s new ballistics lab custom built each load for suppressor usage each load features the cleanest and quickest powder for the caliber to help keep suppressed firearms as clean as possible while maintaining subsonic velocities and maintaining reliability. Freedom Munition’s HUSH ammunition line was designed from the ground up to provide the best in affordability, reliability and cleanliness in suppressed pistols and rifles.
