Abstract
The invention is ammunition and ammunition components labeled so that either a projectile or a shell casing found at a crime scene can be associated with all documented handlers from the last documented recipient back to the manufacturer. The likely labeling code is a two-dimensional binary array with at least six cells (digits) in each dimension. Several different methods of imparting the label to a projectile at or near its rear end are described, some of which can be used in combination, including: adding a labeled identification member beneath the projectile'"'"'s rear surface, embossing the projectile'"'"'s rear surface, injecting pins through the projectile'"'"'s rear end, embossing the projectile beneath the projectile'"'"'s rear surface at a transition between metal layers of different melting temperatures, printing the projectile'"'"'s rear surface with detectable material, etching the projectile'"'"'s rear surface. Several different methods of imparting the label to the cylindrical wall of a shell casing are described, some of which can be used in combination, including: indenting from the outside to produce a braille-like symbol, printing on the outer surface with detectable material, printing on the inner surface with detectable material, etching on the outer surface, etching on the inner surface.
