Sorry to be paranoid, but if the technology exists to make scratches on bullets that are exact duplicates for use in testing, does not the ability also exist to produce a bullet supposedly from a shooting victim that’s an exact match to one fired from your gun?

Fingerprints and DNA are useful in solving crimes because they are both unique and permanent. The “fingerprints” that a gun puts on the cartridge case and bullet may be unique, but they are not permanent. Spending 2 minutes at the chamber and muzzle with a small file will completely change the “fingerprint” of the case and the bullet.
