Consecutive & Random Manufactured Semi-Automatic Pistol Breech Face & Fired Cartridge Case Evaluations

The objective of this project is to evaluate the impression markings on cartridge cases fired from semi-automatic pistols to determine to what extent these markings can be used to match with a particular firearm and whether they can be interpreted in the same way as the random striations on fired bullets. Using optical and confocal microscopy techniques and a specific set of firearms, the researchers plan to identify and quantify the surface of the cartridge cases in terms of class, subclass and random characteristics. ca/ncf
