Winchester W357ST Silvertip 357 Magnum 145gr JHP Ammo 20rd Box

The Winchester W357ST Silvertip delivers proven stopping power with its 145-grain jacketed hollow point design engineered for controlled expansion and deep penetration. This premium .357 Magnum ammunition combines Winchester's legendary Silvertip technology with consistent performance across multiple shooting applications.

What Makes This Different

The Silvertip jacket hollow point construction creates a controlled expansion pattern that maintains weight retention while producing reliable terminal performance. Unlike standard hollow points that may over-expand or fragment, the Silvertip design balances expansion with penetration depth. The 145-grain bullet weight provides optimal velocity while managing recoil in both revolvers and lever-action rifles.

Key Features

• 145-grain Silvertip jacketed hollow point bullet for controlled expansion
• Premium brass cases with consistent powder charges for accuracy
• Boxer-primed cases suitable for reloading applications
• Compatible with .357 Magnum revolvers and lever-action rifles
• Nickel-plated bullet jacket resists corrosion and feeds smoothly
• Factory-loaded to SAAMI specifications for reliable performance
• 20 rounds per box, 10 boxes per case (200 total rounds)

Field testing demonstrates consistent accuracy with this load, making it suitable for hunting medium game, personal defense, and competitive shooting. The bullet design performs effectively through various barrel lengths, from 2-inch snub-nose revolvers to 20-inch carbines. Weather-resistant components maintain reliability in adverse conditions, while the controlled expansion characteristics provide predictable terminal ballistics.
