New ‘Quiet-22′ Rimfire Ammo from CCI — Just 68 dB of Noise
How would you like to be able to shoot a rimfire rifle or pistol that only makes 25% as much noise as a standard .22 LR gun? And no, we’re not talking about a suppressor-equipped firearm. CCI claims that its new Quiet-22 rimfire ammo “generates one-quarter the perceived noise level of standard velocity .22 LR rounds.” So this stuff is very quiet indeed, and it’s also affordable — a 50-round box sells for under $4.00 at major online vendors.
CCI’S 710 fps Quiet-22 Ammo only produces 68 Decibels (dB) of sound at the shooter’s ear (compared to 132-139 dB for a standard .22LR). How do we put that in perspective? Consider this: 68-70 dB is the noise level inside a typical family sedan cruising at 70 mph. For additional comparisons, a typical alarm clock ringer produces 80 dB of noise, while a hair dryer can deliver 90 dB. The sound levels at rock concerts can top 115 dB, and a chain saw can hit 125 dB.
To achieve its low sound levels, CCI’s Quiet-22 ammo sacrifices both speed and energy. Rated velocity is just 710 fps, and the 40gr LRN bullet only has about 36 ft-lbs of energy at 100 yards. So this ammo may not be a great choice for varminting, except for very small prey. On the other hand the ammo could be ideal for short-range plinking and fun shooting. For paper punching, CCI notes that Quiet-22 ammo offers better performance than an air rifle with similar noise levels. CCI’s Quiet-22 Ammo may also be perfect for areas where shooting is allowed, but noise pollution is a concern.
Do You Need To Wear Muffs?
CCI says you can shoot this ammo without hearing protection. The 68 dB report of this ammo is well below the 85 dB(A) noise level at which OSHA requires hearing protection in the workplace. However, remember that, when you’re at a range with other shooters, you must shield your ears from the noise produced by other firearms. So even if you use Quiet-22 ammo, you’ll need muffs/plugs if other shooters nearby are using conventional rimfire and centerfire ammo.
