Abstract:
1. A method for enhancing the delivery of a projectile from a weapon to an intended target comprising the steps of Providing a projectile suitable for firing from the weapon, said projectile including an open leading end and a trailing end, an ogive defined on said leading end, and a longitudinal axis extending between said leading and trailing ends, said leading end including a meplat cavity extending toward the interior of said projectile substantially concentric with said longitudinal axis for a preselected distance from said leading end, said meplat containing a quantity of non-uniformly distributed extraneous jacket material disposed therein, reducing the overall length of said projectile from its leading end to its trailing end to a preselected value which is optimal for developing a completed round of ammunition embodying the projectile, said value being constant from projectile to projectile, and defining a substantially annular planar outermost face on said leading end of said projectile, said annular planar outermost face being disposed in a plane which is substantially perpendicular to said longitudinal axis of said projectile, thereafter, while said projectile is maintained in a stationary attitude, substantially simultaneously cutting away and removing extraneous material disposed within said meplat cavity from said projectile to define an excavated meplat cavity having a void volume of a predetermined depth and inner circumferential geometry, said excavated meplat cavity having a longitudinal centerline which is substantially concentric with the longitudinal centerline of the projectile.
