Ballistics doesn't work as well as it used to. The basic theory is that cut rifling leaves a unique set of tool marks in the gun barrel which in turn transfer to the bullet. This falls apart with modern industrial production with cold hammer forged barrels and polygonal rifling. At that point the best you could say is the bullet came from a Glock, and matches 5000 barrels forged on a specific mandrel. The police would be happy to charge based on that but the defense could tear it apart. Even with older rifling methods ballistic doesn't work as well as it does on TV. The State of Maryland used to require a fired bullet and case from every pistol registered to allow matching ballistics, but quit doing when they realized they had never actually used this warehouse full of evidence in a prosecution.
