CCI Low Noise rounds are used for training or special applications when noise is a factor. They are clean-burning, low velocity ammo with a noise level much like an air rifle. CCI has an industry exclusive in the Pest Control/Specialty line 22 WRF with a jacketed hollow point bullet. This load combines a 19th century favorite with 21st century technology and is ideal for old barrels. Note: Not recommended for use in revolvers.
