CCI is known for producing high-quality rimfire ammo, and the Quiet-22 ammunition is no exception. When compared to conventional velocity rounds, this silent cartridge gives a report that is 1/4 the perceived noise level, making it ideal for backyard plinking, youth shooting, or shooting in regions where noise is an issue. This round is suited for bolt-action or single-shot rifle shooters (but is perfectly safe in semi-automatics although it might not completely cycle the action). This subsonic ammo is ideal for shooting through your rimfire suppressor of choice. CCI Quiet ammo is non-corrosive and brand new.
