Hornady 300 Blackout Subsonic Ammunition is designed for accuracy and performance below the speed of sound. The new 190 gr Sub-X (Subsonic - eXpanding) bullet features a lead core. Long grooves in its gilding metal jacket combine with the bullet’s flat profile and the patented Flex Tip insert within its hollowpoint cavity to help it expand reliably at low velocities. Performance of the Hornady Subsonic 300 Blackout load meets or exceeds FBI Protocol terminal ballistic test requirements. 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. Impact velocity of 1,020 fps into ballistic gelatin provides 16-18”; penetration and 90%+ weight retention. 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.
