In an effort to provide law enforcement with modern crime fighting tools, a new patentpending bullet identification technology known as the Ammunition Coding System (ACS) has been developed. ACS assigns a unique code to every round of ammunition manufactured, and by recording sales records, law enforcement personnel will be able to easily trace the ammunition involved in a crime and have an avenue to pursue and solve even the most difficult cases. The key to ACS is the unique code that is micro-laser engraved on factory-produced ammunition. This laser engraving is etched on both the projectile and the inside of the cartridge casing. Each code will be common to a single box of cartridges and unique from all other ammunition sold. The unique ACS codes will be tracked and records maintained to identify individual ammunition purchases. The ACS technology will provide a method for law enforcement personnel to trace ammunition purchases and link bullets and cartridge cases found at crime scenes to the initial retail ammunition purchaser. This system will not necessarily prove who pulled the trigger, but it will provide law enforcement with a valuable lead and a starting point to quickly begin their investigations. The design of the ACS laser engraving system will allow law enforcement personnel to identify the bullet code in cases where as little as 20% of the bullet base remains intact after recovery. Since bullets are designed to keep the base solid and in its original configuration, the likelihood of ACS codes remaining legible after recovery is very high. Law enforcement testing has already shown a 99% success rate in identifying the ACS code after bullet recovery.
