Two-Pronged Study of Bullets Fired by Consecutively Rifled Barrels
In this study, firearms examiners were asked to use traditional microscopic methods to identify unknown bullets to the appropriate barrels. Additionally, 3D scans of these bullets were used in a matching algorithm to find similarity scores between bullets. Error rates were determined and the potential for subclass carry-over among the barrels was evaluated.
