The RWS SUBSONIC HP is a special cartridge for low-noise shooting. The bullet velocity stays distinctly below the sound barrier - consequently there is no sonic boom. For this reason, this rimfire cartridge is very well suited for weapons with silencers. It offers similar good shooting performance as a standard cartridge, but with significantly less noise. Due to the hollow tip, this ammunition achieves a sure and reliable effectiveness with small game and varmints. Not suitable for selfloaders.
