Modern personal defense demands ammunition that performs reliably in real-world conditions. Low flash, consistent ballistics, and dependable expansion through clothing are critical factors for anyone selecting defensive rimfire rounds for home defense or carry in small platforms. Tactical-minded shooters need data-driven reasons to trust a load before it spends a case in the chamber.

HORNADY CRITICAL DEFENSE is designed specifically for those requirements. The FTX Flex Tip sits at the heart of this load, promoting rapid, reliable expansion while preventing the hollow point from clogging when passing through layers of clothing. Nickelplated cases increase visibility in low-light handling and feeding, and lowflash propellants reduce muzzle flash that can disrupt night vision. This rimfire option from Hornady is offered in various models and configurations to suit compact defensive platforms and training needs. Shop this product

Key features that matter on duty and at home

FTX Flex Tip technology

The molded polymer Flex Tip maintains a streamlined profile for reliable feeding and initiates consistent expansion on impact. For defensive use, that predictability in terminal performance is the primary advantage; it keeps energy transfer efficient without overpenetration in typical household scenarios.

Nickelplated cases

Nickelplating improves corrosion resistance and makes rounds easier to pick up and identify in low light. For operators who value tactile speed and clean feeding in compact rimfire platforms, this treatment reduces the chance of failures from environmental contaminants.

Lowflash propellants

Reduced muzzle flash preserves night vision and reduces visual signature when deploying in dark environments. That trait is especially important for close-quarters defensive encounters where preserving situational awareness after the first shot is essential.
