Timeline of Ballistics Examination. 1923:. FBI Bureau of Forensic Ballistics established. 1929:. weapons used in the St. Valentine’s Day massacre identified by matching bullets. What is Forensic Ballistics. Any projectile is considered ballistic evidence.. These include bullets, arrows, objects launched from a slingshot etc.. Most often the scientist is looking at bullets.. The goal is to match a projectile with the weapon it came from.. 9. /3/15. Bellwork. How are you going to make a match between the crime scene bullet casing and test fired ones?. Ballistics p.34-35. Topic: Casings. Evidence: Match caliber and firing pin impressions to crime scene guns.. 9. /4/15. Bellwork. What part of identifying the casing is the hardest for you?. Closure. What did you learn about the casings by doing this lab?. Bellringer 4/14/15. What is ballistics?. The study of bullets and firearms.. Bellringer 4/14/15. Ballistics Notes .

Residue- Bullet holes or GSR (the gunshot residue). Three components of Ballistics:. Bullets can be identified by the unique pattern the barrel made. Each gun has a different barrel.. With new chapters, homework problems, case studies, figures, and examples, Ballistics: Theory and Design of Guns and Ammunition, Third Edition encourages superior design and innovative applications in the field of ballistics. It examines the analytical and computational tools for predicting a weapon\'s behavior in terms of pressure, stress, and velocity, demonstrating their applications in ammunition and weapons design. New coverage in the Third Edition includes gas-powered guns, and naval ordinance. With its thorough coverage of interior, exterior and terminal ballistics, this new edition continues to be the standard resource for those studying the technology of guns and ammunition.
