![]() CCI Stinger: Introduced in 1976, the CCI Stinger brought.Shotshells: Shotshells are a special type of 22LR ammunition that mostly used for hunting & target sports.Subsonics: Subsonic rounds are rounds that do not break the sound barrier.Hollow Point or Round Nose: If you are plinking, target shooting or hunting for fun, round nose or ballistic rounds are generally preferred. ![]() (Just thought that was a neat thing to share) ![]() However, your rifle will still go bang and the quieter ammo will not have the punch to knock down the bigger game. Subsonic cartridges produce less noise than full velocity rounds. Without getting into the scientific details, most gun experts say that subsonic ammor is not only quiet but more accurate at close range due to no turbulance from the bullet breaking the sound barrier. Heres some gee whiz information if you didn’t know about the subsonic. The main focus is on sound marksmanship, so be sure to practice and be safe. This story isn’t an advertisement on Ruger 10/22, but they do make awesome 22 rifles. 22 round into the temple of the hog and puts it down on the spot. Like a seasoned hunter Jim waited for the hogs to show and loitering at the bait area.įrom 50 yards away Jim spots the big hog among others that had been giving them problems on his property in the past. To be exact he was sporting a suppressed Ruger 10/22 rifle equipped with an ATNX-Sight for night vision. 223 caliber bolt-action rifle firing low-velocity (subsonic) ammunition using a GEMTECH G5-5.56 suppressor.Ĭompared to the high-velocity (supersonic) unsuppressed condition, the combination of subsonic low-velocity ammunition and a firearm suppressor provided a reductions of 45, 38, 40, and 48 dB, peak sound pressure level at the muzzle, left, right ears and behind the shooter, respectively.What is surprising is that Jim was only using a subsonic. The peak sound pressure levels of a Remington 700. 223 caliber bolt-action rifle firing high-velocity (supersonic) ammunition using a GEMTECH G5-5.56 suppressor. Specific reductions depend on the ammunition and suppressor. Main article: Suppressor § Subsonic ammunition and reduced sonic signatureĬombined with firearm sound suppressors, subsonic ammunition may significantly reduce sound levels compared to normal ammunition. These are designed from the start as dedicated subsonic projectile systems. 45 ACP ammunition load, of a 230 grain bullet at 850 feet per second, is naturally subsonic.Īlternatively, specialized firearms and ammunition may be used to optimize total subsonic ammunition effectiveness. For example, the traditional American military standard. Some ammunition types were inherently designed with heavier, slower standard bullet weights and velocities. Subsonic ammunition with normal bullet weights often fails to properly function in such firearms. Subsonic loads for 9mm commonly use 9.5 grams (147 gr) bullets at velocities of 300 metres per second (980 ft/s).įor these ammunition loads, balancing bullet weight and velocity are required to ensure that the ammunition will still reliably cycle semi-automatic firearms. In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound.Īs an example, the very common 9×19mm Parabellum standard military round is a 7.5 grams (116 gr) bullet at velocities typically around 360 metres per second (1,200 ft/s). Standard calibers Subsonic versions of standard rounds 1.1 Subsonic versions of standard rounds.
