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.Ītomic’s Tactical Cycling Subsonic in 5.56x45mm produces similar energy and power as 9mm cartridges and delivers CQB accuracy from rifles with barrel twist rates of 1 in 7″ or faster. Sub 223 and 308 drop like a rock anyways.

Unsuppressed, it is as quiet as most 22 LR and has minimal felt recoil. Re: subsonic 223 that cycles I was making some 223 reduced loads a while back that would cycle my Ar15. Making some 223 subsonic ammo to shoot throw my suppressed. For sure 223 is one of the worse cartridges for subs, as its really designed to do the opposite, but its fun to try out. Atomic’s Tactical Cycling Subsonic is unlike traditional high powered rifle ammunition. Any subsonic powjectile in a 223 case wont cycle in a standard semi-auto, as the powder required to stay subsonic is about 1/4 of the standard charge. Are 223 subsonic reloads capable of cycling AR-15 pistol Or go 300 AAC Blackout I have searched in the archives but dont find a lot of data on this. Twelve and 13 grains eject but dont have enough power to cycle another round into the chamber. Any subsonic powjectile in a 223 case wont cycle in a standard semi-auto, as the powder required to stay subsonic is about 1/4 of the standard charge.
