You retrieve a pistol or rifle that you keep for home defense purposes and - when the target presents themselves - shoot them.īesides the trauma of a home invasion, they also suffer hearing damage and a joyful spot of tinnitus. The intruder is armed, and has made clear their intentions of coming in. Someone starts breaking into your home while you and your family are clearly there. Subsonic Ammunition And Home DefenseĪnother potential use of subsonic ammunition is in home defense. If you're going to be burning a heck of a lot of brass at the range, it's fantastic.Īnother use worth mentioning is small game hunting, as 22 subsonic loads can drop below 120 dB, with some even below 100 dB. Thus, you can shoot plenty with a heck of a lot less punishment on your ears. However, it is safer than 160dB+ without ear protection.
Subsonic rounds with suppressor pro#
That doesn't mean you can shoot without ear pro 120 dB is still not a safe noise level for extended periods. A gunshot that normally produces 160 dB+ of noise could potentially be reduced to 120 dB of noise or even further, depending on all the circumstances involved. When combined with a further 20 dB noise reduction with low velocity ammunition, the net result is a healthy reduction of noise level. They don't silence a gunshot they just make them a little quieter, usually only providing a reduction of about 20 dB to 30 dB of noise. If you're going to run a can on your handgun or rifle, concurrent use of subsonic ammunition will get you the greatest noise reduction.Īs we know, suppressors in and of themselves are basically a muffler that goes on the end of a gun. With that said, what purposes are there for low-velocity subsonic ammunition? Subsonic Ammunition Is Ideal For Use With A Suppressor So when people say "subsonic".it might not mean what you think it means.
Hush Puppy 115-gr ammunition is loaded to 1000 fps, about 150 fps slower than typical 115-gr ammunition. However, again, it depends a heck of a lot on the loading and what gun it's fired through.įor instance, SuperVel Hush Puppy 147-gr 9mm (made for use with suppressors) is loaded to 900 fps, which is around 50 to 100 fps slower than typical 147-gr ammunition. Depending on the loading and the gun used in said ammunition, the noise level produced by the gunshot might be as low as 130 dB, or lower. However, there are also low-velocity subsonic loadings that produce less noise, due to the projectile being far slower than heavy-for-caliber loadings. Same story for rifle ammunition and shotgun ammunition. 45 ACP and heavy-for-caliber 9mm ammunition still produces around 160 dB of noise when fired, which - if not wearing hearing protection - produces instant and irreversible hearing loss. 40 S&W loads, such as 147-grain 9mm or 180-gr. 45 ACP, with few exceptions, is almost exclusively subsonic. Anything faster is supersonic, anything at or around that speed is transonic, and anything below that velocity is subsonic.Īs it happens, a lot of handgun ammunition is in and of itself subsonic. Technically, any ammunition that achieves less than supersonic velocity is in and of itself subsonic, which is 1,126 ft per second. The word "subsonic" is much like other things in the gun community where there's a technical meaning and then there's a colloquial meaning, and you had better know the difference between them or else you might get yourself in trouble. There's Subsonic Ammunition And Then There's Subsonic Ammunition But with that said, let's talk about what you can use it for and when subsonic ammunition is called for. In fact, just because a round is subsonic doesn't mean it's all that quieter. This doesn't mean you can or should shoot it without ear protection, of course you should wear hearing protection at all times while shooting. Bear in mind that not all ammunition that is inherently subsonic is necessarily quiet, however. It has uses, many of which are practical beyond merely being quieter than a typical gunshot.
However, subsonic ammunition, like a hollow point, is a tool with an intended purpose. As it happens, a heck of a lot of handgun ammunition is inherently subsonic, but that doesn't necessarily mean much! Subsonic Ammunition: What It Is, Why It's UsefulĪmmunition that's loaded so that the projectile travels under a certain velocity threshold is subsonic in that the bullet doesn't break the sound barrier.
