Liberty Ammunition Ultra-Light Features The Liberty Ammunition Ultra-Light projectile is engineered to create the maximum amount of tissue disruption with a single round using a deep hollow cavity that fills with fluid on impact until hydraulic pressure causes the side walls of the bullet to burst outward. That explosive expansion produces a rifle-sized temporary wound cavity along with hydrostatic shock increasing stopping power well beyond what a standard hollow point delivers. Following the initial expansion the projectile fragments into a starburst pattern that creates multiple separate wound channels rather than a single straight path. This combination of effects is designed to stop a threat quickly while also reducing the risk of over-penetration and the unintended casualties that can come with it. Driving a 50 grain bullet at 1500 fps the Ultra-Light s lighter weight projectile produces noticeably less muzzle flip than a standard-weight .380 ACP load letting shooters get back on target faster for follow-up shots if needed. The two-piece nickel alloy case is twice as strong as traditional brass while weighing only half as much shaving overall cartridge weight without sacrificing case integrity under pressure. Lead-free construction keeps the round cleaner to shoot and handle compared to traditional lead-core ammunition. Packaged 20 rounds to the box this Liberty Ultra-Light load is built for everyday carry pistols chambered in .380 ACP.
