Silence, stealth and proven performance. That's what you get with Hornady® Subsonic Sub-XTM Ammo. Shoot without the loud report and pair it up with a suppressor for even quieter shooting. Benefit from optimized powders for subsonic use which result in a low flash signature. And this Ammo meets or exceeds FBI Protocol terminal ballistic test requirements: impact velocity of 1,020 FPS into ballistic gelatin provides 16-18” penetration and 90%+ weight retention. Additionally, the new 190-gr. Sub-XTM (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 help provide reliable expansion at low velocities.
