Liberty Ammunition Ultra-Light 380 50 Grain Hollow point Shell Shock Cased Pistol Ammo 20 Rounds. Weve combined our innovative Civil Defense projectiles with Shell Shock Techs groundbreaking new cases to create the ultimate self-defense rounds. It has more kinetic energy than a lot of 45 ACP self-defense rounds except its more convenient than any self-defense round in todays market. 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 fewer muzzle flips for faster follow-up shots. The cases are a two-piece nickel alloy shell that is twice as strong as brass and only half the weight.
