A webinar presented during the Forensic Technology Center of Excellence (FTCoE0 Firearm and Toolmark webinar series on the progress of our CSAFE project. This study assesses the production of subclass characteristics during the manufacturing of breech faces by three different methods. Observations on how well subclass characteristics persist on manufactured breech faces with and without any finishing methods. Observations on the effect of the primer on the quality/quantity of the breech face impression will be discussed.
