1. An ammunition cartridge configured to be fired from a weapon's barrel, the cartridge incorporating a projectile comprising:
(1) an elongated metal jacket having a trailing edge;
(2) a swaged core encapsulated by the elongated metal jacket; and
(3) a non-pyrotechnic tracer formed into a metal disk, the disk having been crimped to, and incorporated into the trailing edge of a jacketed projectile, precisely incorporating and securing the crimped tracer disk, to be oriented perpendicular to the axis of rotation of the projectile, wherein the tracer is embossed with a retroreflective morphology, having an array of retroreflectors, oriented in the jacketed bullet so that the focal apertures, in the disk, of the arrayed retroreflectors, in the tracer, are oriented to have a parallel alignment of the rotation of axis of the projectile, and
wherein observable projectile assembly maximizes the intensity of light returned along the axis of rotation of the projectile that when illuminated by an observer or tracking instrument in the vicinity of the weapon optimizes the intensity of light reflectance allowing for measurement and observation of actual drift and drop of the projectile in flight.
