RUAG's .300 Whisper weapon systems have been much appreciated by special units for the precise and quiet firing of shots in the urban environment for over twelve years. The exclusive European supplier of ammunition of this caliber offers even more with the new supersonic version .300 Whisper SWISS P HV Styx Action. At an operative range of approximately 150 meters, special police and military units use the .300 Whisper primarily in urban areas against secondary targets such as alarm systems, fighting dogs or cameras. The deformation ammunition .300 Whisper SWISS P HV Styx Action (HV=High Velocity) widens the application spectrum and provides highly precise hits also at 300 meters. The range of ammunition enables the shooter to move from subsonic to supersonic by a magazine change within seconds in order to remain efficient and convertible.
