Liberty’s Civil Defense rounds are designed to achieve more stopping power (kinetic energy) and terminal effect (wound cavity/lethality) than any other handgun round. A personal defense round the Civil Defense line is lead-free and uses a monolithic nickel-plated copper fragmenting projectile with a deep cavity hollow point in a nickel-plated (brass) cartridge case. Civil Defense travels at approximately twice the speed of traditional lead based ammunition and delivers 30 to 40% more kinetic energy transfer than other leading ammunition. – Caliber: 45 Colt – Bullet Type: Hollow Point – Bullet Weight: 78 gr – Muzzle Energy: 560 ft / lbs – Muzzle Velocity: 1800 fps – Rounds Per Box: 20
