Description
Hornady Critical Defense 22 Winchester Magnum Rimfire (WMR) Ammo 45 Grain Hornady FTX Polymer Tip – Best Price is a purpose-built defensive load engineered for rimfire platforms where terminal performance is mission-critical. This is for the shooter who carries a .22 WMR for personal protection and demands reliable expansion from a rimfire cartridge. Its key differentiator is the Flex Tip technology, which prevents clogging and ensures consistent terminal ballistics through barriers.
Key Features
- FTX Polymer Tip: The Flex Tip initiates rapid, controlled expansion upon impact. This matters because it maximizes energy transfer and creates a larger wound channel than standard hollow points, which is vital for stopping power in a rimfire caliber.
- 45-Grain Weight: This specific weight provides an optimal balance of velocity and momentum for the .22 WMR case capacity. It matters because it helps maintain reliable cycling in semi-automatic firearms while delivering sufficient mass for penetration.
- Nickel-Plated Cases: The cases resist corrosion and provide smoother feeding. This matters for a defensive round that may be carried for extended periods and must function flawlessly under stress.
- Critical Defense Formulation: Hornady’s specific propellant blend is designed for consistent velocity and clean burning. This matters for shot-to-shot reliability and maintaining your firearm’s performance.
