Hornady Subsonic Ammunition .300 BLACKOUT 190 gr SUB-X 1050 fps 20/ct

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.
