Federal Premium MSR Ammunition 300 AAC Blackout 190 Grain Fusion Polymer Tipped Box of 20

Hornady 300 Blackout Subsonic Ammunition is designed for accuracy and performance below the speed of sound. The 190 grain 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 hollow-point cavity to help it expand reliably at low velocities. Performance of the 300 Blackout Subsonic load meets or exceeds FBI Protocol terminal ballistic test requirements.
