Hornady 90511 Critical Duty 357 Mag 135gr FlexLock Ammo 25rd

The Hornady 90511 Critical Duty ammunition delivers barrier-blind performance engineered specifically for law enforcement and personal protection applications. This 357 Magnum load features the advanced FlexLock bullet design that maintains expansion and penetration consistency through intermediate barriers.

What Makes This Different

Critical Duty ammunition incorporates Hornady's FlexLock bullet technology with an InterLock band that mechanically locks the core and jacket together. Unlike traditional hollow points that can clog with clothing or drywall, the Flex Tip initiates expansion while the InterLock band prevents jacket-core separation. FBI protocol testing validates this load's ability to penetrate 12-18 inches in ballistic gelatin through heavy clothing, wallboard, plywood, and automotive glass.

Key Features

• 135-grain FlexLock bullet with Flex Tip for reliable expansion initiation
• InterLock band mechanically locks jacket and core preventing separation
• Nickel-plated brass cases resist corrosion and enhance extraction
• Low-flash propellant reduces muzzle signature in low-light conditions
• FBI protocol tested for barrier penetration and terminal performance
• Crimped and sealed primer prevents moisture contamination
• 25 rounds per box, 10 boxes per case (250 total rounds)

This load generates approximately 1,275 fps muzzle velocity from a 4-inch barrel, delivering 487 foot-pounds of energy. The 135-grain weight provides manageable recoil while maintaining sufficient mass for deep penetration. Critical Duty performs consistently in revolvers and lever-action rifles chambered in 357 Magnum, making it suitable for law enforcement patrol rifles, backup revolvers, and civilian personal protection firearms.
