Hornady's Critical Defense .22 WMR 45gr FTX Ammo stands out as a purpose-built self-defense round for compact rimfire firearms. If you're seeking a reliable cartridge for personal protection in a small-frame revolver or semi-auto, this ammunition delivers. The nickel-plated casing ensures smooth feeding and corrosion resistance, crucial for carry rounds that may be exposed to moisture over time. The 45-grain FTX (Flex Tip eXpanding) bullet is engineered to perform consistently through barriers like heavy clothing, addressing a common shortcoming of standard hollow points in this caliber.

With a velocity of 1000 fps and 100 ft-lbs of muzzle energy, this load packs a surprising punch for its size. While not traditionally considered a self-defense caliber, the .22 Magnum gains new relevance with this specialized loading. For rural property owners looking for a low-recoil option to deal with small predators or pests, this ammunition offers a practical solution. The controlled expansion of the FTX bullet enhances terminal performance without sacrificing penetration, making it a versatile choice for those who need a single load to serve multiple roles. When every ounce counts in your everyday carry setup, this compact yet capable round deserves serious consideration.
