Hornady Subsonic .300 AAC Blackout 190gr Sub-X Subsonic Flex Tip eXpanding 20/Box is designed for accuracy below the speed of sound, and when paired with a suppressor, it’s even more quiet. Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance. The Sub-X bullet (projectile) features a lead core with long grooves in its gilding metal jacket, which combined with the bullet’s flat profile and the patented Flex Tip insert within its hollow point cavity help it expand reliably at low velocities. Performance of this ammunition meets or exceeds FBI Protocol terminal ballistic test requirements and delivers devastating, threat-ending performance. This ammunition is built for defense purposes and for hunting medium sized game (50 to 300 lbs) including whitetail deer. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases.

Please Note: Subsonic loads are ideal for shooting through suppressors because they help reduce the sound signature. Subsonic rounds do not exhibit a supersonic crack making them quieter when shot through your favorite can. These loads do not have to be fired through a suppressed firearm and will function in non-suppressed firearms.
