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: 10mm AutoBullet Type: Hollow Point (HP)Bullet Weight: 60 grMuzzle Energy: 780 ft lbsMuzzle Velocity: 2400 fpsRounds Per Box: 20Boxes Per Case: 10Application: Performance,ProtectionCasing Material: Nickel-PlatedBullet Coating: Nickel-PlatedHazair: YesAmmunition cannot be shipped to a P.O.
