the bullet is engraved by the rifleing but there is no way match it to a gun without having the gun to provide a sample bullet to compare
i suppose they could come up with some kind digital rifling button
with 6 grooves say you could vary each one with a large medium or small cutter that would be like 700 different combos add an extra large and and extra small you coudl really narrow down the search of suspects and its pattern could just be encoded in the serial number
