  1. Forensic Ballistics Introductory Notes

  2. What is Forensic ballistics? • Forensic ballistics attempts to establish the true facts in a shooting crime • Ballistic evidence includes • Firearms • Bullets • Cartridge cases

  3. Major Types of Ballistic Evidence • Bullet holes • Bullet damage • Bullet trajectories • Gunshot wounds

  4. Internal Ballistics • Internal Ballistics studies all of the processes inside a firearm. • Most common responsibilities are: • Examining firearms in case of accidental discharge • Examining homemade devices called zip guns • The microscopic examination of fired bullets and cartridge cases

  5. External Ballistics • External ballistics studies the projectile of the bullet from the gun to target. • Two common types of external ballistics are: • Calculation and reconstruction of bullet trajectories • Establishing the maximum range of a given bullet

  6. Terminal Ballistics • Terminal ballistics is the study of the projectiles effect on the target. • The target can be any solid or living object • When the target is human or animal this is often referred to as “wound ballistics”

  7. Types of Terminal Ballistics • Determination of distance between firing and target • Establishing whether a particular wound was caused by a fired bullet • Determining the caliber and type of projectile that caused the wound • Identifying exit/entrance by examining holes in targets or wounds • Examination of ricochet possibilities on targets and fired projectiles
