Lehigh Defense Xtreme Defense 357 Mag 120gr Monolithic Ammo 50rd

The Lehigh Defense Xtreme Defense 357 Magnum ammunition delivers maximum terminal performance through its innovative fluid transfer monolithic design. This 120-grain cartridge creates permanent wound channels significantly larger than conventional hollow points while maintaining deep penetration. The solid copper construction ensures consistent expansion and weight retention across various barrier materials.

What Makes This Different

The Xtreme Defense projectile features machined flutes that channel fluid radially outward upon impact, creating tissue disruption comparable to expanded hollow points without relying on bullet deformation. This monolithic copper design maintains structural integrity through heavy clothing, drywall, and automotive glass where traditional expanding bullets often fail. The 120-grain weight provides optimal velocity in standard 357 Magnum revolvers while reducing felt recoil compared to heavier loads.

Key Features

• Fluid transfer monolithic copper construction for consistent terminal performance
• 120-grain projectile optimized for 357 Magnum chamber pressures
• Machined flutes create permanent wound cavities without bullet expansion
• Barrier-blind performance through clothing, glass, and light barriers
• Reduced copper fouling compared to plated bullets
• Temperature-stable powder charge for consistent velocities
• Nickel-plated brass cases for reliable extraction and corrosion resistance

Field testing demonstrates consistent 1,400+ fps velocities from 4-inch barrels with excellent accuracy across various revolver platforms. The solid copper construction eliminates core separation issues common with bonded bullets, making this ammunition suitable for law enforcement duty use, personal protection, and hunting medium game. The monolithic design functions reliably in both snub-nose and full-size revolvers without feeding concerns.
