Ballistics and or Rifling is the science that deals with the motion of projectiles such as bullets, shells, rockets, and aerial bombs. It is important to police officers who investigate crimes involving shootings in order to match the gun to the bullet. It is also important to artillerymen, naval gunnery officers, and to engineers who design firearms, missiles, bombsights, and fire-control systems.
This is the marking that is left on the bullets or projectile. All guns leave a unique spiral scratch or marking on the bullet as it fires. Police use this as a way to link bullet casings to the gun that fired it
The exterior ballistics are any factors that will effect the bullet while in flight Wind Gravity Air resistance Drift Even the temperature and air density play a factorSpecialized bullets are used to reduce these factors such as different weights and sizes as well as groves put into the bullet or the shape of the bullet
The study of terminal ballistics is the study of how a projectile behaves after it hits the target The studies of this are done to help defend against enemy attacks, and to prove the efficiency of a weapon The most common test for this is the use of ballistic gel
This gel is specially formulated to simulatehuman body density, this is used to test anddemonstrate how a persons body will react to aBullets impact, and how much damage a bullet will do toa person’s body
Using Ballistics in court can be used on both sides of the argument The defense can use it to prove that the bullet fired was not linked to a defendants gun It can also link the criminal to the crime and prove that he/she was at the crime scene and fired the shotFingerprints on shell casings is the best way to link a bullet person who fired it but it is not always accurate.
