For those looking to plink with their.22 LR rimfire guns without the added noise, the CCI Quiet-22 22 Long Rifle ammunition is the perfect choice for a silent day at the range or in the woods. The ammunition is loaded with a 40-grain Segmented HP bullet that travels at only 710 fps, far slower than the speed of sound, and produces a muzzle energy of 45 foot-pounds. This ensures that the round produces 75 percent less report than a standard.22 LR rifle round. The ammunition ships in boxes of 50. Mfg: Cci.
