Hornady 300 Blackout 190gr Sub-X Subsonic Rifle Ammunition

Hornady Subsonic 300 Blackout ammunition is engineered for optimal accuracy and terminal performance below the speed of sound. Featuring the patented Sub-X bullet design with a lead core, it incorporates long grooves in the gilding metal jacket and a flat profile with a Flex Tip insert to ensure reliable expansion at subsonic velocities.

Formulated with specialized propellants, this ammunition delivers clean-burning consistency from lot to lot while minimizing muzzle flash signature. The reduced sound report makes it exceptionally quiet when paired with a suppressor, yet it remains fully functional and effective in unsuppressed firearm configurations.

Built to meet or exceed FBI Protocol terminal ballistic test requirements, this cartridge utilizes premium Hornady cases and primers for dependable ignition and feeding. It provides trusted precision and stopping power for medium game hunting and personal defense applications.
