However, broadly speaking, if you want sound reduction, the best 9mm suppressor ammo is pretty much any name brand, subsonic 9mm. For a person with a home defense carbine in 9mm, the best 9mm suppressor ammo will be wildly different. The peak sound pressure levels of a Remington 700. For the Gemtech Auror 2, the best 9mm suppressor ammo is the standard NATO ball or subsonic ball ammo. 223 caliber bolt-action rifle firing high-velocity (supersonic) ammunition using a GEMTECH G5-5.56 suppressor. The peak sound pressure levels of a Remington 700.
Specific reductions depend on the ammunition and suppressor. 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. As previously mentioned, the only thing required for a traditional AR-15 using. But, it is also available in subsonic cartridges, which makes it much quieter when fired. 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. Rounds are available in supersonic form that can be quietened through the use of a suppressor. 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.This is the perfect round for shooters looking to reduce the noise of each shot even more,” said Brett Flaugher, Winchester Ammunition vice president of marketing, sales and strategy. “Suppressed firearms are growing in popularity. M-22 Subsonic will be available in 100-round plastic packs and 800-round bulk packs. With the addition of a suppressor, M-22 Subsonic achieves a remarkably quiet 116 db. Subsonic 9mm ammunition is engineered to have a velocity below the speed of sound. 22 LR fired from a suppressed rifle, which typically measures around 138 db. The lineup of 9mm subsonic ammo for sale includes the most innovative rounds from the industry’s best manufacturers, ensuring every shot is consistent and right on target.
#Best subsonic rounds full
That is significantly quieter than a full velocity. During Winchester testing, M-22 Subsonic rounds measured 129 dB from an unsuppressed rifle. Nosler 80-grain bullet and Titegroup performed best with subsonic velocities but would not work the AR action. The M-22 Subsonic was also created with suppressed firearms in mind, but performs just as well in unsuppressed rifles and handguns. In addition, the M-22 Subsonic utilizes non-corrosive priming and clean burning powder for reduced muzzle flash. The new M-22 Subsonic features a 45-grain black-plated lead round nose bullet that has the equivalent energy of full velocity 36-grain rimfire products. The M-22 is designed specifically to function in semi-automatic firearms, while remaining subsonic from both pistol and rifle length barrels. In 2016, Winchester Ammunition continues to invest in its rimfire product line with the development of a new M-22 Subsonic. Winchester Ammunition delivered one of the most significant innovations to hit the rimfire world in 2013 with the introduction of the 17 Winchester Super Magnum, but where new rimfire loads are concerned, the company is far from over.
