Title: Cartridge Case
Description: This cartridge case shows the three distinct marks, or 'signatures,' impressed on its surface when it was fired by a gun: the firing pin impression (FP), the breech face impression (BF) and the ejector mark (EM). NIST's standard casing ensures that forensic labs can accurately match signatures on shells found at crime scenes with images in a national database.
