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 1020 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.
