Firearms Manufacturing & Corresponding Toolmarks

The toolmarks left on the cartridge cases and bullets give us varying information regarding the types of tools used during the manufacture of a firearm. In this class we’ll explore how and why we can use specific toolmarks left on cartridge cases and bullets in our same source identification conclusions.

Topics covered in this course include:
• Common Manufacturing & Finishing Processes
• Identifying these processes on fired components
• Which Toolmarks to use in our Conclusions and Why
