300 AAC Blackout bullet in Subsonic Handgun has built a world-class reputation for accuracy and stopping power. Performance of Sub-X Centerfire Rifle Ammunition Subsonic meets or exceeds FBI Protocol terminal ballistic test requirements. If you need the quietest firepower possible for sneaking up on game, arm yourself with some dependable Hornady 300 Blackout 190gr Sub-X Subsonic Rifle Ammunition – 500 Rounds 300 AAC Blackout 190gr Sub-X Centerfire Rifle Ammo is designed with the patented Flex Tip insert within its hollow point cavity for reliable expansion even at lower velocities. This 300 Blackout Ammo from the professionals at Hornady features special powders that deliver a low flash signature, and when combined with a silencer, this ammunition provides maximum stealth for sneaky hunts. Features of The Hornady Subsonic Ammunition 300 AAC Blackout 190 grain Sub-X Centerfire Rifle Ammunition lets your efficiency do all the talking. Unique powders optimized for subsonic use result in a low flash signature, ideal for either suppressed or unsuppressed performance. Hornady® Subsonic Ammunition doesn’t have the loud report of a supersonic round, and paired with a suppressor, it’s even quieter. Hornady® Sub-X Centerfire Rifle Ammunition - designed for accuracy and performance below the speed of sound - now comes in both rifle and handgun loads. 300 AAC Blackout has a lot of consistency from lot to lot. 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, Powders are selected for optimal performance and the Subsonic. The Sub-X bullet used in Subsonic Rifle features a lead core. Nosler 80-grain bullet and Titegroup performed best with subsonic velocities but would not work the AR action. 300-AAC-Blackout Subsonic Handgun utilizes tried-and-true XTP® bullets that expand reliably at subsonic velocities.

The peak sound pressure levels of a Remington 700. 223 caliber bolt-action rifle firing high-velocity (supersonic) ammunition using a GEMTECH G5-5.56 suppressor. On the subsonic side, the first dot is good to 50 yards and the second dot is good out to 150 yards. The first dot is good to 100 yards with supersonic ammo, and the second goes out to 300 yards. The dots correspond with bullet drop for both subsonic and supersonic projectiles. Specific reductions depend on the ammunition and suppressor. This reticle is the 68 MOA circle with two 1 MOA dots in the center. Main article: Suppressor § Subsonic ammunition and reduced sonic signatureĬombined with firearm sound suppressors, subsonic ammunition may significantly reduce sound levels compared to normal ammunition. These are designed from the start as dedicated subsonic projectile systems. 45 ACP ammunition load, of a 230 grain bullet at 850 feet per second, is naturally subsonic.Īlternatively, specialized firearms and ammunition may be used to optimize total subsonic ammunition effectiveness. For example, the traditional American military standard. Some ammunition types were inherently designed with heavier, slower standard bullet weights and velocities. Subsonic ammunition with normal bullet weights often fails to properly function in such firearms. Subsonic loads for 9mm commonly use 9.5 grams (147 gr) bullets at velocities of 300 metres per second (980 ft/s).įor these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound.Īs an example, the very common 9×19mm Parabellum standard military round is a 7.5 grams (116 gr) bullet at velocities typically around 360 metres per second (1,200 ft/s). Standard calibers Subsonic versions of standard rounds 1.1 Subsonic versions of standard rounds.
