Description
The Winchester USA White Box .22 Long Rifle (.22 LR) 36-grain Copper-Plated Hollow Point (CPHP) 333-round bulk pack is a high-velocity rimfire cartridge designed for high-volume target shooting, training, and small game applications. A persistent friction point in rimfire systems is heavy lead fouling combined with inconsistent semi-automatic cycling, which degrades accuracy and triggers failures to feed or extract over extended firing strings. Winchester completely addresses this operational bottleneck through a copper-plated projectile and a high-velocity pressure curve, maintaining cleaner bore conditions and stable action function across various rimfire platforms.
The technical advantage comes from the direct interaction between projectile construction and internal ballistics. Launching its lightweight 36-grain payload at a supersonic muzzle velocity of 1,280 FPS, this load offers flat trajectories and reliable action-cycling backpressure. Mechanically, the copper plating reduces direct lead-to-bore contact, limiting the rapid fouling accumulation that degrades rifling engagement and requires constant cleaning. Upon target contact, the engineered hollow point geometry promotes immediate, controlled expansion, making it highly effective for dropping small game and backyard pests cleanly.
Operating at a swift 1,280 FPS, this cartridge generates the necessary slide velocity and backpressure required to cycle finicky semi-automatic handguns and rifles consistently. Built for extended range sessions, the ammunition utilizes clean-burning powders and reliable, non-corrosive rimfire primers to minimize carbon buildup. This keeps your action running smoothly with fewer interruptions for maintenance or malfunction clearing. Packaged in a convenient, cost-effective 333-round bulk value box, this configuration is an ideal choice for high-volume shooters looking to maximize range time without sacrificing downrange performance.
Key Benefits
- 333-Round Bulk Box: High-volume value packaging keeps your rimfire actions supplied for long training sessions and varmint eradication tasks.
- Fouling-Reducing Copper Plating: Micro-thin copper exterior minimizes raw lead transfer inside the rifling to preserve match-grade accuracy over long firing loops.
- Expanding Hollow Point Nose: Specially engineered hollow cavity initiates rapid and uniform expansion on impact to dispatch small game humanely.
- Calibrated High-Velocity Impulse: Supersonic 1,280 FPS velocity curve ensures crisp, uniform backpressure to cycle finicky semi-automatic slides and carriers.
