Federal AE Suppressor 9mm ammunition features a subsonic 124 Grain Full Metal Jacket bullet, a non-corrosive primer and virgin brand new never fired brass casing. Federal American Eagle Suppressor 9mm ammo offers a muzzle velocity of 1030 feet per second.
Is subsonic ammo less accurate?
So while the energy to cleanly kill small game remains, the downrange crack vanishes. And as smallbore competitors know, subsonic . 22 LRs are more accurate than supersonic . 22s because they exhibit 37 percent less wind deflection due to the disproportional increase of air resistance near the sound barrier.
Do Special Forces use subsonic ammo?
In its latest round of small-business solicitations, the Pentagon’s Special Operations Command, or SOCOM, is seeking out subsonic ammunition. Commandos have used subsonic bullets since World War II, though these are mainly effective in smaller guns like the . 22 and 9 mm caliber pistols.
What is the quietest gun with a silencer?
The De Lisle carbine or De Lisle Commando carbine was a British firearm used during World War II that was designed with an integrated suppressor. That, combined with its use of subsonic ammunition, made it extremely quiet in action, possibly one of the quietest firearms ever made.

What grain 9mm is subsonic?
Subsonic versions of standard rounds Subsonic loads for 9mm commonly use 9.5 grams (147 gr) bullets at velocities of 300 metres per second (980 ft/s). For these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms.
What 9mm ammo is subsonic?
Most 147 grain 9mm rounds are subsonic and thus have heavier weights and are slower velocity rounds, usually less than 1,000 feet per second (fps.)
Is 1000 fps subsonic?
Technically, any ammunition that achieves less than supersonic velocity is in and of itself subsonic, which is 1,126 ft per second. That’s the speed of sound. Anything faster is supersonic, anything at or around that speed is transonic, and anything below that velocity is subsonic.
What calibers are subsonic?
Specialized subsonic calibers. Alternatively, specialized firearms and ammunition may be used to optimize total subsonic ammunition effectiveness. These are designed from the start as dedicated subsonic projectile systems. Some examples include .300 Whisper / 300 AAC Blackout (7.62×35mm), .338 Whisper, 9×39mm, 12.7×55mm STs-130, .510 Whisper .
What’s difference between subsonic and supersonic?
In context|of a speed|lang=en terms the difference between subsonic and supersonic is that subsonic is (of a speed) less than the speed of sound (in the same medium, and at the same temperature and pressure) while supersonic is (of a speed) greater than the speed of sound (in the same medium, and at the same temperature and pressure).
What is the effective range of subsonic ammunition?
Re: What is the effective range of subsonic ammunition According to a guy named Billy Dixon the effective range of subsonic ammunition is about 1 mile.
Why use subsonic 9mm ammo?
Subsonic ammunition is loaded specifically for the projectile to maintain a speed that does not break the sound barrier and create a sonic crack. 9mm, for example, is generally considered supersonic as most 9mm ammo has a muzzle velocity over 1100 FPS.
