The soaring popularity of suppressors as well the need for new bullets designed specifically for subsonic performance have led Hornady to develop its new 300 Blackout Subsonic Ammunition. 

Loaded with the all-new 190 gr. Sub-X bullet (Subsonic-eXpanding), the ammo was designed to perform terminally and accurately below the speed of sound. Along with a lead core and a cannelure for a positive case crimp, 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. Additionally, a low flash signature makes the ammo ideal for both suppressed and unsuppressed firearms. And because of the growing use of 300 Blackout in law enforcement and for military applications, Hornady made sure the performance of the new load meets or exceeds FBI Protocol terminal ballistic test requirements.
