Description
Hornady Critical Defense Triple Defense .410 bore 2.5″ shotshells are built around a stacked projectile column intended for short-range defensive use in compact pistols and derringers chambered for .410. The load combines two .35-caliber round balls beneath a .41-caliber FTX slug to produce a concentrated pattern at close distances. Cases are described in supplier material as nickel-plated on many production runs, and the propellant choice is optimized to limit recoil and muzzle flash for small-frame firearms. This load is sold in 20-round boxes and is positioned for home/short-range defensive applications.
