Key Features and Benefits
- FTX Polymer Tip: The Flex Tip technology initiates consistent expansion while preventing clogging from clothing or barriers
- Optimized Ballistics: The 45-grain projectile maintains velocity and energy for effective terminal performance
- Reliable Ignition: Specially formulated primers ensure consistent ignition in all conditions
- Clean Burning: Advanced propellants reduce fouling and maintenance requirements

Technical Specifications and Performance
The Hornady Critical Defense 22 WMR ammunition delivers approximately 1,550 feet per second muzzle velocity from a rifle-length barrel, generating around 240 foot-pounds of energy. The FTX bullet design creates a controlled expansion pattern that maximizes tissue damage while maintaining adequate penetration depth. This balance makes it particularly effective for defensive use where over-penetration concerns must be balanced with stopping power.
