"And if you ever want to calculate how much louder you perceive one sound as compared to another you can do it by using the following formula. I started buying a few boxes of this stuff here and there when I see it on the shelves. At 50 yards, the CCI SV Target held its own with one ragged hole especially for the price of 4.99 a box vs the other brands at 15 to 17.50 per box. *Rule of thumb taken from here: Converting Decibels to Sound Intensities Without getting in too deep with other name brands, I tried Lapua, Eley, and SK to name a few. So looking at the different ammo Dbs levels above (not suppressed) the difference from the cci blazer to the cci quiet is about 10db, which equates to about half the perceived sound. That's a massive difference (and yes, we already know this without the math ha ha). So if we use this rule of thumb*: "2 x (db reduction /10) = perceived reduction in sound", then a 30db reduction would be a perceived sound level 6 times less. 22 silencer options and most of the ones that I saw claimed a 31 to 34db reduction. Most suppressors claim from 30-40 db reduction. I'll try to repeat this with a suppressor in the future and maybe shoot more shots with each bullet type.ĬCI standard velocity - 1070 fps 40 gr - 101.9 dBĬCI target 22 short - 830 fps 29gr - 92.9 dBįYI not trying geek out about sound, but I did find some good resources about how much sound reduction suppressors make. Obviously taking an average of more rounds would give more accurate results but I couldn't be bothered. Keep in mind that dB scale is logarythmic so even small changes can be quite dramatic to the ear (not going to get into details of percieved noise blah blah blah). All shots from the same spot and same target. Sound level measured with Iphone app (NIOSH) about 15' away and to the side of the gun. While the 22 CB tends to jam in most semi-automatic firearms due to its limited charge, it performs well in bolt-action rifles, revolvers and single-shots.For those of you curious about the sound levels of 22 ammo here are the results of a simple, non-scientific test I did today.ĭB levels of various cci 22 rounds in a HK/Walther 416 pistol (9" barrel). With no report to speak of, nuisance animals and small game don’t seem to detect the sound, which means stealthier hunting. What about the lesser-known 22 CB? While this round doesn’t have the thump or range of the 22 LR, it’s about as loud as a pellet gun and still packs enough of a wallop to dispose of garden pests or bring down small game such as rabbit and squirrels. Great for target practice and small game hunting, CCI’s 22 Long promises consistent accuracy and a muzzle velocity that’s faster than the 22 Short but around 425 fps slower than 22 LR. 975 inch long, and the 22 Long measures about. It uses a 22 LR case, but the bullet is shorter. The second-most popular of the sub-22 LR rounds is the 22 Long. Others use the round strictly for plinking-after all, the 22 Short was used in shooting galleries at fairs and arcades in until fairly recently. Many 22 lovers also prefer the 22 Short’s hushed nature and lower power for teaching new shooters. This means reduced range, making the 22 Short a logical choice for suburban pest control and close-quarters small game hunting. Coming out of the muzzle at 1,105 fps, CCI’s 27-grain Short Hollow Point rounds post a velocity that is significantly less than, say, 32-grain 22 LR Stingers, which leave the muzzle at 1,640 fps. A stone-cold pest killer, the 22 Short is less noisy than the 22 LR and requires less of backstop. It works great in suburban hunting environments. The 22 Short is now coveted by plinkers and small-game hunters. In fact, until 2004, the round was used in the Olympics by those competing in the 25-Meter Rapid Fire Pistol Event. Created for self-defense when fired from a pocket pistol like the classic Derringer, the 22 Short evolved into other realms. The 22 Short is a stellar round that serves a variety of purposes. Yet, despite such performance and the versatility to plink cans, punch paper and snipe small game, it hasn’t managed to drive its shorter brethren into extinction. It’s generally loaded with heavier bullets than 22 Long, Short and CB, and its rounds offer low recoil, solid range and mild report. The 22 Long Rifle is the kingpin of rimfire cartridges.
