Product Overview
Winchester Super X .22 Winchester Magnum Rimfire (WMR) 40-grain Jacketed Hollow Point ammunition is engineered for consistent terminal performance across a range of applications, including varmint control and precision target practice. This ammunition integrates advanced development techniques with established manufacturing processes to ensure dependable function and ballistic consistency.
Key Features
Projectile Design
The 40-grain Jacketed Hollow Point (JHP) projectile is precisely designed to achieve controlled expansion upon impact. This design facilitates efficient energy transfer, optimizing terminal effect and promoting rapid incapacitation. The jacketed construction maintains bullet integrity for consistent penetration while ensuring reliable expansion within target medium.
Propellant and Priming
Each cartridge utilizes a carefully metered propellant charge, calibrated for consistent velocity and pressure regulation. Non-corrosive rimfire priming ensures reliable ignition across diverse environmental conditions, contributing to the overall system’s dependability and shot-to-shot consistency.
Case Construction
The brass casing is manufactured to stringent specifications, ensuring consistent dimensions for reliable feeding, chambering, and extraction across compatible firearm platforms. This precision in case construction mitigates potential cycling issues, enhancing operational reliability.
Manufacturing Standards
Winchester’s Super X line leverages advanced development techniques and innovative production processes. This comprehensive approach ensures tight manufacturing tolerances throughout the cartridge assembly, which is critical for achieving the stated ballistic output and consistent performance.
