Product Overview
The Winchester USA White Box .22LR ammunition, offered in a 333-round bulk pack, provides a high-volume solution for diverse rimfire applications. Engineered for consistent performance, this ammunition supports rigorous training regimens, general recreational shooting, and practical small game acquisition.
Key Features
Bullet Design & Terminal Performance
Each round integrates a 36-grain copper-plated hollow point projectile. The copper plating serves to mitigate lead fouling within the bore, thereby supporting consistent ballistic profiles and reducing long-term maintenance requirements. The hollow point cavity is engineered for controlled expansion upon impact, optimizing energy transfer for effective use against small game and varmint species.
Ballistic Consistency
Manufacturing protocols emphasize predictable ballistic performance across production lots. This design consideration ensures reliable cycling and accuracy across a spectrum of rimfire firearm platforms, from dedicated precision rifles to pistols equipped for skill development or conversion kits for personal defense firearms.
High-Volume Utility
The 333-round packaging configuration facilitates extended range sessions, making it suitable for both foundational and advanced skill development without frequent resupply interruptions. This bulk quantity supports cost-effective, high-round-count training scenarios.
