Liberty Ammunition Spike Features Liberty Ammunition Spike is built around a 100 percent copper lead-free projectile featuring an integral spike that is designed to drive deep penetration and create a permanent wound channel on impact. At 55 grains the bullet is dramatically lighter than a standard 115 or 124 grain 9mm projectile allowing it to reach a muzzle velocity of 1900 feet per second while producing significantly less felt recoil. This combination of light weight and high velocity is intended to deliver fast controllable follow-up shots in a self-defense scenario. The open cavity design behind the spike works with the projectile s shape to maximize terminal performance at these velocities. The cartridge uses Liberty s NAS3 nickel-plated brass casing which is engineered to be lighter to carry than conventional brass casings without sacrificing the reliability of a brass-cased round. Being lead-free this ammunition may also be a consideration for shooters practicing at indoor ranges with lead restrictions. Delivering 441 foot-pounds of energy at the muzzle this load channels its light fast-moving projectile into meaningful stopping power for personal defense applications. Liberty Ammunition markets this Spike load as one of the more powerful and specialized options in the 9mm Luger self-defense category.
