The Rifling and the Scientist
In the field of forensic ballistics, studies have significantly shown that no two firearms are alike; that is, no two firearms when firing ammunition leave the exact same marks as another (on said ammunition), even if that other is an identical model from an identical manufacturer. This makes it very easy for experts in the field to differentiate between weapons in the same fashion that fingerprints differentiate between individual people.
How does this all work though i hear you ask?
