The CCI Suppressor Rimfire Ammo 22 LR Subsonic HP delivers whisper-quiet performance for shooters who use suppressors, with the Subsonic HP series engineered to run reliably in suppressed semi-automatic firearms while producing significantly less muzzle report thanks to its 970 fps subsonic velocity and clean-burning powders that reduce blow-back and ease firearm cleaning. This 45 gr lead hollow point offers dependable expansion at low velocities, translating to effective terminal performance for pest control, small-game hunting, and backyard range use where sound management matters, and the brass casing maintains consistent feeding and extraction across platforms. With a muzzle energy of 94 ft-lbs, CCI Suppressor balances controllable ballistics with the terminal effects expected from a hollow-point bullet, and the ammunitions design minimizes disturbance to fellow shooters or neighbors during training sessions or maintenance drills. Made in the United States and labeled under the Subsonic HP sub-brand, this round is a go-to for range safety officers, hunters working close-range woods shots, and suppressor owners seeking reliable, low-noise 22 LR hollow-point performance.
