Chamber marks are toolmarks frequently encountered on fired cartridge cases. Chamber marks are used on a regular basis to make identifications. Although chamber marks are used for comparison purposes, only a handful of articles have been published regarding their value for identification purposes in casework. The goal of this research project is to provide the Firearm and Toolmark Identification community with a resource for information on the persistence of chamber marks over an extended number of firings.
