3. *Ballistics The term ballistics refers to the science of the travel of a projectile in flight. The flight path of a bullet includes: travel down the barrel, path through the air, and path through a target. Internal travel: within the firearm External travel: from firearm to target Terminal travel: hitting the target

4. *Questions To Be Considered What sort of weapon was involved? From what distance & direction was it fired? What type of projectile was fired? Can the projectile be matched to the weapon? Can the cartridge case be matched to the weapon? Was the shooting accidental or deliberate? Who fired first?

17. Caliber *Caliber of bullet is referring to the size of the bullet in inches, or millimeters. A ".357 Magnum" has a bullet which is, as you probably guessed -.357 of an inch in diameter. A "9mm"

18. Theory of Firearm Identification Marks produced by the random imperfections or irregularities of tool surfaces, corrosion, or damage. They are unique to that tool and distinguish it from all other tools.* Bullets and cartridge cases can be compared using marks left on them through their contact with a firearm. * Association of Firearm and Tool Mark Examiners Glossary 4th Edition
