The Hornady 300 Blackout 190 gr Sub-X® Subsonic ammunition is engineered for accuracy and performance at velocities below the speed of sound. Loaded with Hornady's 190 grain Sub-X® (Subsonic eXpanding) bullet, this load combines subsonic performance with a projectile specifically designed to provide reliable expansion at low velocities.
The Sub-X® bullet features a lead core surrounded by a gilding metal jacket with long grooves that help facilitate expansion. A patented Flex Tip® insert sits within the hollow-point cavity to help initiate expansion at subsonic velocities, while the bullet's flat profile contributes to its low-velocity performance. A cannelure provides a positive case crimp for reliable use in semiautomatic firearms.
Hornady developed its Subsonic ammunition for shooters looking for dependable performance below the speed of sound. The 300 Blackout 190 gr Sub-X® load is built around the characteristics of the cartridge while pairing it with a purpose-designed expanding projectile rather than a conventional non-expanding subsonic bullet.
