Winchester USA 22 LR 36 Grain Copper Plated Hollow Point (MPN: 22LR555HP)
Rimfire shooters, small-game hunters, and high-volume target marksmen know that finding an economical, high-velocity .22 Long Rifle load capable of cycling semi-automatic pistols and rifles without heavy lead fouling is essential for long range days. Winchester engineered their USA 36-grain Copper Plated Hollow Point (CPHP) bulk load to solve this problem directly. Packed in a high-capacity 555-round box, this high-velocity cartridge provides hunters and plinkers with hard-hitting terminal energy on small game and clean-running operation across a variety of rimfire platforms.
Every round features a 36-grain hollow-point bullet coated in a protective copper plating. This copper wash dramatically reduces lead deposit build-up in the bore and suppressor baffles while enabling high-velocity flight without bullet deformation. Winchester seats these projectiles in quality brass cases loaded with clean-burning propellants and reliable non-corrosive rimfire priming, ensuring fast ignition and consistent internal pressures from the first round to the last.
Out on the range or in the field, expect flat trajectories, snappy action response, and rapid target acquisition. Pushing a muzzle velocity of 1,280 FPS, this high-velocity load generates the optimal slide and bolt momentum needed to cycle semi-automatic handguns, tube-fed carbines, and magazine-fed rifles reliably. The hollow-point nose cavity initiates rapid terminal expansion on varmints and small game like squirrels and rabbits, making this 555-round value pack an unbeatable choice for pest control, field hunting, and all-day target shooting.
Armorer Bench Notes & Technical Maintenance Guidance
Shipping Restrictions: Ammunition sales are strictly regulated. Check all state and local laws prior to ordering. Cannot ship to PO Boxes, APO/FPO addresses, or internationally. Must ship via ORM-D / Hazardous Ground transport.
Armorer Tip: High-velocity 22 LR copper-plated ammunition helps minimize bore lead deposits, but high-volume bulk shooting still leaves wax and powder fouling inside receiver mechanisms and magazine lips. Regularly clean your semi-auto rimfire firing pin channels, extractor hooks, and feed ramps every 500 rounds to prevent stovepipe malfuntions or misfires caused by light firing pin strikes.
