Winchester 357 Magnum 145gr Silvertip HP Ammo - 100 Rounds

The Winchester WB357S145X delivers proven stopping power with 145-grain Silvertip hollow point bullets engineered for controlled expansion and deep penetration. This premium .357 Magnum ammunition combines Winchester's decades of manufacturing expertise with modern ballistic technology to provide consistent performance across multiple platforms.

What Makes This Different

Silvertip hollow point construction features an aluminum tip that initiates rapid expansion upon impact while the jacket design controls deformation for optimal weight retention. Unlike standard hollow points that can plug with clothing or debris, the Silvertip design maintains expansion reliability across various barrier materials. Each cartridge delivers approximately 1,290 fps muzzle velocity from a 4-inch barrel, generating 535 ft-lbs of energy.

Key Features

• 145-grain Silvertip hollow point bullets for controlled expansion
• Aluminum tip prevents hollow point plugging through barriers
• Nickel-plated brass cases resist corrosion and ensure smooth feeding
• Compatible with all .357 Magnum and .38 Special +P rated firearms
• Boxer-primed cases suitable for reloading applications
• Consistent powder charges for shot-to-shot velocity uniformity
• 100-round bulk packaging reduces per-round cost

Field testing demonstrates reliable expansion at velocities between 900-1,400 fps, making this load suitable for both revolver and carbine applications. The 145-grain weight provides flatter trajectory than heavier bullets while maintaining sufficient mass for barrier penetration. Law enforcement agencies have documented consistent performance in duty applications, while hunters appreciate the balance of expansion and penetration on medium game.
