Atomic's Tactical Cycling Subsonic is unlike traditional high powered rifle ammunition. Unsuppressed, it is as quiet as most .22 LR and has minimal felt recoil. These relatively innocuous-sounding cartridges, with their low recoil and report, serve professionals with an alternative to much louder standard power rifle cartridges allowing faster follow-up shots and better full auto accuracy with the added safety of not penetrating level 2 and higher armor worn by many law enforcement and military professionals.
