Hornady’s Critical Defense Ammunition is the pinnacle in self-defense ammunition. Using a variation of the materials used in the revolutionary LEVERevolution® line of ammunition, Hornady engineers achieved 100% reliable expansion when shooting through even the toughest clothing barriers. Conventional hollowpoint bullets have had issues with the cavity clogging from clothing fibers, which hinder them from expanding in soft tissue after going through a cloth barrier. The soft polymer insert in the tip of the bullet is what prevents this from happening. Nickel cases eliminate corrosion and premium low-flash propellents that deliver maximum velocity and impact.
