Increase in velocity with the suppressors installed, due to the marginalīoost the residual pressure inside the suppressor gives the bullets. The pistols bare and then with suppressors on them. 22 and 9mm ammo I tested is loaded to be subsonic while theĪsym. I used my Doublestar rail gun and put an Innovative Arms Shepherd on it.įor the rimfire testing, I went with a Ruger. Gathered up a selection of subsonic ammunition and suppressor-equippedįor the 9mm, I grabbed a Nighthawk and a Gemtech GM-9. Should not expect problems shooting subsonic ammunition through a Pushing their bullets, and they craft the bullets accordingly. Very small margin for weight, and if they do adjust it, it isn't byĪmmunition manufacturers know at what velocities they will be That if they ease up too much, reliability will suffer. Small amount and let velocities slip just below supersonic. So to make rimfire ammo subsonic, they ease on up the powder charge by a Rimfire ammunition makers know if they deviate from the standardĤ0-grain bullet weight at normal velocities they do so at their peril. 22 pistolsĪre infamous for being very fussy about ammunition-both in terms of Here, theĪmmo companies are between a rock and a hard place because. Subsonic for use in handgun suppressors is. The last cartridge we might commonly encounter that would be loaded 380īallistics and defeats the purpose of having a 9mm in the first place. Really want to be pushing 124-grain or 115-grain full-metal-jacketīullets at 950 fps? The latter is getting perilously close to. It is also possible to have lighter bullets be subsonic, but do we You wouldn't want to shoot it because recoil would be stout. Searching to find any 147-grain or heavier bullet 9mm Luger load thatĭelivers supersonic velocities out of a handgun barrel. And there a trend that began in 9mm ammunition some time agoĬomes to our rescue: 147-grain bullets. To keep the speed under the limit, we have to increase bullet Almost all 9mmĪmmunition will exceed the speed of sound-or be so close on theirĪverage that one or two in each magazine will be over the speed limit. When we get to 9mm, things get interesting. You want ultra-quiet AOs, you can't go 165 grains or lighter. Lighter bullets, however, will often exceed the speed of sound, and if You can select from will commonly be around 900 to 950 fps at most. For instance, the shelves full of 180-grain FMJs Similarly, the normal 180-grain ammunition in most. Used them when it comes time to clean your suppressor.) (Suppressors hate cast bullets, and you will hate having You can even load your own, provided you don't useĬast bullets. Much pick any of them and have subsonic ammunition without having to payĮxtra for it. 45 ACP, forĮxample, has only a few loads that exceed 1,116 fps, so you can pretty At standard atmosphericĬonditions, the speed of sound is 1,116 fps, and because any singleīatch of ammo is going to vary somewhat in velocity, most subsonic stuff Modern add-on suppressors do not decrease bullet velocity, whichīrings us back to subsonic ammunition. It is released into the baffles, and for the most part the gas no longer Once the bullet leaves the muzzle, the gas propelling Muzzle of your handgun, and the clearance hole down the center of theīaffles is larger than the diameter of the bullet so the bullet does not Tubes with internal partitions called baffles. That, let's look at how a suppressor works. So it's quiet, but how does it perform? Before we get into The speed of sound, so the supersonic "crack" (which a To make a suppressor as quiet as possible, you need to useĪmmunition known as subsonic. Gun club (the suppressors, not the supermodels). Here and they are hot, and you're going to be seeing them at the Supermodels, not all agree about liking or disliking them. Noticed that suppressors are the hot new thing. IF YOU HAVEN'T BEEN PAYING ATTENTION, you might not have APA style: The suppressor factor: does a suppressor slow bullets or inhibit their performance?.The suppressor factor: does a suppressor slow bullets or inhibit their performance?."
