The CCI Quiet-22 Semi-Auto 22 LR 45 gr LRN delivers a low-velocity, low-noise rimfire option thats ideal for backyard plinking, training new shooters, and range sessions where reduced report matters, and it cycles reliably through semi-automatic rifles and handguns while maintaining excellent accuracy. This Quiet-22 series cartridge uses a 45-grain lead round nose bullet seated in brass casing and produces about 835 fps and roughly 70 ft-lbs of muzzle energy, giving shooters a shooter-friendly trajectory and reduced recoil that mimics the feel of shooting suppressed without adding a can. Shooters looking for a quieter range experience will appreciate how the reduced perceived noise helps with follow-up shots and better communication on the line, while hunters testing wind or sight-in loads can trust consistent performance from a trusted American-made CCI round. Whether you operate a semi-auto trainer for youth instruction, want low-recoil practice for sighting in optics, or need a less-disruptive target round for populated ranges, this Quiet-22 Semi-Auto offers reliable cycling, predictable ballistics, and the trusted name recognition of CCI for dependable rimfire performance.
