Liberty Civil Defense 40 S&W 60gr HP Handgun Ammo - 20 Rounds - Liberty's projectiles function differently than any other self defense round on the market. They designed the Civil Defense line to eliminate threats with one round. They 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 flip for faster follow up shots. All of Liberty's rounds are also lead free and California compliant. Less Felt Recoil More Velocity and Kinetic Energy Reduced Over-Penetration 2000 FPS
