Subsonic 9mm primers1/20/2024 ![]() Bullets reach supersonic speeds at around 1,130 fps at sea level with a temperature of around 70 degrees. ![]() The solution to this problem is simple: ammunition that doesn’t create a sonic signature because it is moving at less than the speed of sound. If you’re a soldier trying to quietly take out a sentry or a rancher hunting a group of feral hogs, this additional noise could mean the difference between success and failure. The muzzle blast is far less pronounced near the shooter, but the overall sound signature is still loud. Hornady’s Subsonic runs at consistent, proper speed, and its XTP bullet is designed to expand at lower velocities.īut here’s the rub: Unless subsonic ammunition is used, even a suppressed firearm will produce a sonic “crack” as it moves through the air. 22 rimfire, it still sounded like a gunshot.Ī suppressor works by temporarily trapping propellant gases inside a system of baffles, effectively flattening the curve of muzzle blast and, therefore, sound signature. Because of my long experience with them, I knew few were as quiet as those you saw in the movies. I grew up in a home with a pretty healthy collection of firearms-and among them was a handful of suppressors. With few players doing it right, Hornady stepped in and built its Subsonic line of ammunition to meet the demand. The rapid growth in suppressor ownership left a gap in the ammunition market, i.e., the widespread availability of quality subsonic ammunition designed specifically to work at such low velocities. So how many suppressors are actually out there? According to the American Suppressor Association, the number stood at 1.8 million as of January. Since there have been a fixed number of transferable machine guns since 1986, it is a safe assumption that the vast majority of those Form 4 applications were for suppressors. If we dive deep into the data published by BATFE in 2017, we can see that the number of Form 4 transfer applications went from 7,024 in 1990 to 133,911 in 2016. Suppressors are regulated by the National Firearms Act, which means that every transfer must be approved. Packaging is marked for Standard or Magnum pistol loads. Consult your reloading manual before reloading.I’m not sure who deserves credit for the explosion in suppressor popularity in this country, but there is little doubt of its occurrence. Winchester guarantees better sensitivity for more positive firing in all guns, carefully-controlled weights of primer mixtures, consistency in size and quality, precise measurements and tolerances for anvil heights, and stability in extremes of temperatures and humidity. Primers are constantly and rigorously tested for consistency and sensitivity at temperatures and conditions far beyond the range of normal usage. These non-corrosive, all-weather primers deliver fast, dependable ignition under any shooting condition. Large Pistol Primers Large Pistol Primers have a unique chemical formula that does not contain corrosive or mercuric compounds. These Pistol Primers are sold in both strips and singles making them ideal for single-stage or advanced reloading. They are Pistol Primers that can be easier to ignite and sit which makes them an excellent option to reload. Large Pistol Primers are highly evolved because of CCI’s continuous evaluation and testing processes. Motor city gun shop offers a Large Pistol Primer.
