With its reduced noise and less recoil, Hornady’s Subsonic makes an ideal training round for new shooters and provides a more enjoyable and successful shooting experience for anyone. The Flex Tip of the Sub-X bullet, combined with long grooves in its gilding metal jacket and the bullet’s flat profile, helps it expand at low velocities with no loss in accuracy. Unique powders for subsonic use result in low flash signature with or without a suppressor. Hornady Subsonic Ammunition is even quieter than a supersonic round. Specifications: 300 Blackout/190 gr Sub-X (SX)/20 Per Box/10 Cs
