"No, once the metal is gone, it's gone. Lead and copper fouling can be removed but the metal that's eroded is gone"

Forensic scientists can read a partial or altered fingerprint and confirm identity of a human, I see no reason why partial rifling would not also identify a gun in the great majority of cases. I understand the gun manufacturer's agree that the bullets would identify the individual weapon.

"Laping the bore with a lead plug and valve grinding compound will also change the markings."

Wouldn't that affect the accuracy? Aren't most bullets lead??? And wouldn't that require an awful lot of work for the average criminal? I also doubt that shortening the barrel by 1/4 inch would significantly alter the markings to defy an expert ballistics guy.
How many rounds wear out a military rifle....???? An M-16 for instance?
