Gun Muzzle/Bullet Groove Match Database
When you buy a gun at a gun shop you need to fire a few rounds to get used to it. After a few rounds or more the inside of the muzzle has permanent grooves that match both the gun and the bullets coming out of the gun for years if not forever with very little change over time. If we photograph both the bullets and the matching inside grooves of the registered gun, we could then build a data base for all guns sold and like finger prints this will help find anyone involved in misuse of said fire arm. Stored on FBI or Government or any Law Enforcement Agency computer the gun would match the person who bought and registered the gun to the person linking them to any crime as an added aid to capturing ciminals.
Reward: Maybe you could give me the first gun using this technology.
