Winchester AmmoCenterfire Handgun Reloading 357 Mag .357 158 gr Jacketed Hollow Point (JHP) 100 Per Box

Winchester 357 Magnum 158 gr jacketed hollow point (JHP) handgun reloading bullets give you the component foundation for building .357 Mag loads tailored to your revolver or carbine. These 100-count boxes deliver the consistent, precision-manufactured bullets serious handloaders need to develop ammunition with predictable ballistics and reliable terminal performance. Whether you're working up target loads, duty rounds, or hunting ammunition, Winchester's engineered bullet design lets you dial in velocity, accuracy, and expansion characteristics specific to your firearm and intended use.

The 158-grain weight is the classic .357 Magnum standard, proven across decades of hunting, law enforcement, and sport shooting applications. JHP construction expands reliably on impact while maintaining controlled penetration—qualities that matter whether you're testing new powders and primers at the reloading bench or preparing ammunition for field work. Winchester's quality control in bullet manufacturing means you get consistent jacket integrity and weight uniformity across all 100 rounds, reducing variables during load development.

Handloaders choose Winchester components for their reputation and performance. These bullets work with standard .357 Magnum reloading dies and are compatible with both revolver and .357-chambered rifle platforms. Start with published load data for your specific powder and primer combination, and you'll have the building blocks for ammunition that shoots the way you want it to.
