The calibre .300 BLK was specifically designed for subsonic shooting in urban terrain. The proportion of the chamber size and the amount of powder are optimised to ensure constant pressure build up and first hit probability. The highly precise loading technique allows a cartridge load very close to the sound barrier, but without risking a supersonic bang. Even at subsonic speed the heavy subsonic bullet provides enough energy to achieve a good terminal target effect. Tight production tolerances and small production batches ensure constant ballistic values and stringent quality controls guarantee identical trajectory from batch to batch.
