1. The method of coding small arms ammunition cartridges having a hollow cylindrical casing having inner and outer wall surfaces including a closed bottom wall having an outer surface, a bullet projectile attached to the forward end of the casing, an explosive charge included in the interior of the casing and a primer to activate the charge positioned on said bottom wall, comprising providing the outer cylindrical wall surface of the casing with a machine-readable code which code identifies such cartridge, assembling said cartridges in an assembly area and moving and orienting said cartridges seriatim into a lighted code reading station including code reading software such that said code is visible to an optical vision system, reading and decoding such code as the cartridges pass through said code reading station, assigning said cartridges a unique tracking number, thereafter placing a number of such cartridges in a retail package and thereafter applying such unique tracking numbers onto said package so that such numbers may be traced to the ultimate purchaser of such package by reading a casing of one of such cartridges when recovered at a crime scene, and, wherein said cartridges are assembled longitudinally side by side in said assembly area and thereafter rolled into said lighted code reading station wherein the resultant turning of the individual cartridges enables the code to be read by the optical vision system. 2. The method of coding small arms ammunition cartridges having a hollow cylindrical casing having inner and outer wall surfaces including a closed bottom wall having an outer surface, a bullet projectile attached to the forward end of the casing an explosive charge included in the interior of the casing and a primer to activate the charge positioned on said bottom wall, comprising providing at least one exterior wall surface of the casing with a machine-readable code which code identifies such cartridge, assembling said cartridges in an assembly area and moving and orienting said cartridges seriatim into a lighted code reading station including code reading software such that said code is visible to an optical vision system, reading and decoding such code as the cartridges pass through said code reading station, assigning said cartridges a unique tracking number, thereafter placing a number of such cartridges in a retail package and thereafter applying such unique tracking numbers onto said package so that such numbers may be traced to the ultimate purchaser of such package by reading a casing of one of such cartridges when recovered at a crime scene, including providing stop means between the assembly area and the code reading station and wherein said stop means is activated by contact with an upstream cartridge.
