Hornady Critical Duty 10mm Auto 175gr FlexLock - 20 Round Box

The Hornady Critical Duty 10mm Auto 175gr FlexLock delivers consistent barrier penetration and terminal performance for law enforcement and personal protection applications. This duty-grade ammunition features Hornady's FlexLock bullet technology engineered to maintain weight retention through intermediate barriers while providing reliable expansion.

What Makes This Different

The FlexLock bullet design incorporates a soft polymer tip that prevents clogging when passing through heavy clothing or barriers, ensuring consistent expansion. Unlike traditional hollow points that can plug with debris, the FlexLock's InterLock band mechanically locks the core and jacket together for 90% weight retention. The nickel-plated brass cases resist corrosion and provide smooth feeding in semi-automatic pistols.

Key Features

• 175-grain FlexLock bullet with polymer tip prevents barrier clogging
• InterLock band locks core to jacket for 90% weight retention
• Nickel-plated brass cases resist corrosion and aid extraction
• Low-flash propellant reduces muzzle signature in low-light conditions
• FBI protocol tested through barriers including heavy clothing, wallboard, and auto glass
• Cannelured bullet with crimped case mouth prevents bullet setback
• Consistent 1050 fps muzzle velocity from 4.6-inch barrel

This ammunition meets FBI penetration standards while delivering controlled expansion in ballistic gelatin. The 175-grain bullet weight provides substantial momentum for barrier penetration while maintaining manageable recoil characteristics in full-size 10mm pistols. Law enforcement agencies specify Critical Duty for its predictable performance through automotive glass, interior walls, and heavy winter clothing.
