Overview
The Winchester Super X X22MH150 22 WMR ammunition provides consistent performance for varmint and small game applications. Engineered with a 40-grain Jacketed Hollow Point (JHP) projectile, this loading delivers reliable terminal ballistics, making it a robust option for target acquisition and field utility.
Key Features
Projectile Design and Performance
Each 40-grain Jacketed Hollow Point bullet is engineered for controlled expansion upon impact, facilitating efficient energy transfer to the target. The JHP design optimizes wound channel creation in varmints and small game, ensuring clean, decisive incapacitation. The jacketed construction enhances projectile integrity and mitigates lead fouling within the bore.
Propellant and Priming System
Winchester utilizes a meticulously formulated propellant blend, calibrated for consistent burn rates across varying environmental conditions. This ensures uniform muzzle velocities, directly contributing to repeatable accuracy and predictable trajectory. The priming system is designed for reliable ignition, a critical factor for operational consistency in rimfire cartridges.
Manufacturing Precision
Production of the Super X 22 WMR cartridges employs stringent quality control protocols. Each round undergoes precise assembly and inspection to ensure dimensional uniformity and optimal component integration. This commitment to manufacturing precision minimizes flyers and enhances overall shot-to-shot consistency.
