If I wanted I could load the 5.56 to subsonic, but I have rounds like the 22 mag that are about the same power so I do not. Or 90% of the time, I just reload my own. But if I want something truly quiet, I can buy both 7.62 x 39 and 300BLK that are loaded down to subsonic. The suppressor lowers the sound to where I am hearing safe without ear protection. Most of the time I shoot them with supersonic ammo, what I would use for hunting or defense. Last, I shoot the carbines like 300 BLK and 7.62 x 39. Most of the 9mm fired out of it will be supersonic, but who cares? It is a little bit more noisy but still hearing safe when run through the suppressor, so I can shoot all day without hearing protection. It uses the same magazines and same ammo as the Glock 19. However, I also have a Keltec Sub 2000 carbine in 9mm. I shoot 9mm out of a Glock 19 with the suppressor on it, almost all factory ammo is subsonic out of the Glock 19.
Subsonic bullet plus#
It costs more, but the reason I buy it us because it is loaded with 45 grain bullets, a plus if shooting animals and I want to be whisper quiet. I have some subsonic 22 and 22 mag labelled ammo. You can actually buy several brands of "Subsonic" labelled ammo, but that is silly, because nearly all the standard velocity rifle ammo will be subsonic when fired out of a short pistol barrel. If you are shooting a 22 pistol for example almost all 22 ammo is subsonic out of the short barrels. I shoot about a dozen rifles suppressed and nearly that many pistols. The slower it goes the less wear on the gun. Your range guy may be talking about some specific brand, but to say subsonic ammo hurts your gun is nuts. At sea level the actual number is about 1127.Įverything You Need to Know About Subsonic Ammo | Field & Stream () For the most part any ammo over 1116 feet per second is considered supersonic, everything below that is subsonic for the purpose of ammo sales. And the industry that sometimes preys on people the way they market ammo, so let me rant a little.Īs Racoon said above ammo labelled subsonic in most pistol calibers is a scam. Because I'll be darned if I can see any reason for spire point bullets otherwise.Click to expand.I get riled up about disinformation that I sometimes hear about suppressors and ammo for them. I'm guessing most bullets are tail-heavy is so that they'll be more likely to tumble once they hit meat, and therefore cause more damage. Then it would maintain stability as it drops through the transonic area. Which seems to be borne out by how bullets behave downrange, and net.lore that loading bullets backwards in the Whisper sometimes works better than sending them out point first.Īn aerodynamically stabilized bullet ought to have the center of pressure behind the center of gravity - that is, like a teardrop or weathervane. When the bullet drops subsonic, the center of pressure moves even farther back, making the problem worse.
So we spin the heck out of them to stabilize them while they fly through the air backwards, for all practical purposes. The typical bullet has the center of pressure (where the shock wave attaches at supersonic speed) pretty close to the center of gravity, or even behind the CG. they're contrary to what I've learned about airflow.
I know most bullets have looked like that for a long time, and they definitely work, but. The popular bullets are all typical boat tail spire points. The idea is for a big bullet going just below supersonic, able to carry a lot of energy downrange at modest velocity. The cartridge was originally intended for subsonic use, though a lot of people load it supersonic.
