Product Overview
The CCI Maxi-Mag 920CC .22 Winchester Magnum Rimfire (WMR) 40-grain Jacketed Hollow Point (JHP) ammunition is engineered for consistent performance and terminal effectiveness across diverse applications. This 125-round offering provides a reliable solution for precision varmint control, small game harvesting, and rigorous target practice sessions.
Key Features
Projectile Design
- 40-Grain Jacketed Hollow Point: Precisely engineered to facilitate optimal energy transfer and controlled expansion upon impact, mitigating over-penetration while maximizing terminal effect.
- Jacketed Lead Core: The projectile features a precisely applied copper jacket over a lead core, contributing to enhanced ballistic stability and consistent downrange accuracy. This construction is critical for maintaining tight group sizes, especially when deployed from precision platforms.
Ignition and Reliability
- Surefire Priming System: Each cartridge integrates CCI’s proprietary Surefire priming system, ensuring reliable ignition and consistent primer strike energy. This minimizes misfires and supports a uniform ballistic trajectory shot-to-shot, critical for predictable performance in varied environmental conditions.
Performance Parameters
- Optimized for .22 WMR Platforms: Formulated for consistent cycling and performance within all standard .22 WMR firearms, from dedicated precision rifles to general-purpose rimfire platforms.
- Consistency in Application: Engineered to deliver predictable results, whether the application demands precision for varmint abatement or reliable function during high-volume range training.
