Our lead-free 223 projectiles function differently than any other self-defense round on the market. We designed the Civil Defense line to eliminate threats with one round. We did this by creating the maximum amount of damage and tissue disruption possible. They do well against barriers, but when the large cavity fills with fluid, the hydraulic pressure builds until the side walls of the projectile explode. With that explosion comes rifle-sized temporary cavities and hydrostatic shock, therefore increasing stopping power by tenfold. Following the explosion, the bullet fragments into a starburst-shaped pattern creating multiple wound channels. This process also benefits in many other areas across the spectrum of things considered when talking about self-defense. Such as reduced over-penetration and lessening the risk of unintended casualties. Having a lighter projectile also leads to less muzzle flips for faster follow-up shots.
