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.

ATTENTION – California Customers
Brownells is still shipping ammunition orders to California but the process has changed to comply with California Proposition 63.
