Hornady Subsonic 300 Blackout 190gr Sub-X 20 Rounds

SUB-X(TM) BULLET TECHNOLOGY- In addition to its patented Flex TipA(R), long grooves in the gilding metal jacket of the 190 gr Sub-X(TM) combine with the bullet's flat profile to ensure expansion. The Sub-X(TM) 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- HornadyA(R) 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.
