Description: Hornady 300 Blackout Subsonic 190gr. Sub-X Ammunition, 20 Round Box. A great option for medium game, this ammunition uses a 190 gr. Sub-X (Subsonic eXpanding) bullet with a lead core. This round has a subsonic muzzle velocity of 1050 feet per second and has 465 foot-pounds of energy at the muzzle. This subsonic ammo is quieter than supersonic ammunition and is even quieter when paired with a suppressor. This round is designed for accuracy and performance below the speed of sound.
SUB-X BULLET TECHNOLOGY
- In addition to its patented Flex Tip, long grooves in the gilding metal jacket of the 190 gr Sub-X combine with the bullet’s flat profile to ensure expansion. The Sub-X features a lead core and a cannelure for a positive case crimp for use in semi-automatics.
PROVEN PERFORMANCE
- Performance of 300 Blackout Subsonic meets or exceeds FBI Protocol terminal ballistic test requirements. Impact velocity of 1,020 fps into ballistic gelatin provides 16-18″ penetration and 90%+ weight retention.
SILENT AND STEALTHY
- Hornady Subsonic Ammunition doesn’t have the loud report of a supersonic round, and paired with a suppressor, it’s even quieter. Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance.
