The supersonic and subsonic bullets draw their names from how they each respectively relate to the sound barrier. In real life, the difference is even more pronounced than in the video. In a lot of calibers it’s actually uncomfortable to shoot supersonic ammo without ear protection, whereas a subsonic load with the same powder charge can be barely noisier than the sound of the action cycling.
#Subsonic rounds vs supersonic crack
In simple terms, subsonic means the bullet is moving slower than the speed of sound, while supersonic means the projectile breaks the sound barrier, producing a sonic crack as it travels through the air. This speed is usually expressed by the Mach number (M) which is the ratio between the air speed and the speed of sound. The speed of sound is a variable thing that is affected by temperature, humidity, and barometric pressure.Īn aircraft designed to fly below the speed of sound is known as subsonic aircraft, while aircraft designed to fly faster than the speed of sound is known as supersonic aircraft. Supersonic means the projectile breaks the sound barrier, which produces a mini sonic boom, or a sonic crack. In very simple terms, subsonic means the bullet is moving slower than the speed of sound.

Subsonic delivers superior stealth and consistency below the sound barrier. Featuring a 38-grain projectile that leaves the muzzle at 1,041 fps, Subsonic is also fast enough to allow it to run in a semiauto without issue. unsafe) load.The company’s 22 Subsonic line is no different, offering shooters consistent performance for small-game hunting and plinking alike. So if you are shooting a stiff load that’s near max pressure without a suppressor, adding the suppressor can easily increase your pressures to make it a warm or hot (i.e. Just keep in mind that when you add a suppressor you raise the pressure of the ammo you are shooting about ~3000-5000 psi.

You can shoot any ammo you want that you would normally shoot, including full power super sonic ammo or subsonic ammo. So, keep this in mind when hunting with a subsonic round.Ī lot of shooters get a suppressor, and think that they now must shoot subsonic ammo. A full power super sonic 308 Win round will have about 6.5 times the energy of a typical SUBSONIC round. The bullet has no expansion and minimal hydrostatic shock. With a standard bullet, the bullet will often, what I call ice pick through your target. Also, at these slower speeds, the bullet will not have any expansion. So, this 308 Win SUBSONIC round has almost the same energy as a 40 cal round, but fired out of a rifle platform. In comparison, a 40 S&W handgun round pushes the same weight 180 grain bullet about the same speed of 1040 fps as a 308 SUBSONIC round does. This round has about 430 ft lbs of energy at the muzzle, and about 380 ft. Take a SUBSONIC 308 Winchester with a 180 grain bullet going about 1040 fps. With these slower speeds, the energy of the round has been heavily reduced. To make a SUBSONIC round, the ammo is loaded to a much lower pressure to keep the bullet below the speed of sound, about 1000-1060 fps. (See “Energy of a SUBSONIC” round below). When shooting this SUBSONIC round suppressed, the suppressor will muffle the bang, and the round will be very quiet. A SUBSONIC round will have no sonic crack. (The reason why a whip has a “crack”, is because the end of the whip breaks the sound barrier). When a bullet goes above the speed of sound (about 1110 fps), the bullet will now have a sonic “crack”, just like the end of a cowboy’s bull whip. When a bullet is going below the speed of sound, there is no sonic “crack” and the bullet has a very quiet flight. To allow for some variables in barrel lengths and such, my subsonic ammo runs about 1000-1060 fps. The speed of sound is about 1110 fps, depending on your exact environmental conditions. SUBSONIC, in terms of ammo, simply means the bullet is going below the speed of sound.
With suppressors being very popular, I wanted to post some information about SUBSONIC ammo and the differences between subs and super sonic ammo, and shooting suppressed.
