How do the lab test whether a bullet from a crime scene came from a suspect weapon?
Forensic scientists compare the bullet's markings (land and groove impressions) with test-fired bullets from the suspect's weapon using a comparison microscope. They look for similarities in striations, rifling pattern, and other unique characteristics to establish a match. Additionally, they may analyze gunshot residue and perform ballistic imaging to further link the bullet to the suspect's weapon.
How does ballistics help police solve crimes?
Rifling marks, the marks etched into a bullet as it travels through a gun's barrel, are to a gun as fingerprints are to a person. To see if a fired round came from a particular gun, the gun is test fired into a pool of water (to stop the bullet without changing its shape) then the marks on the test fired bullet and the bullet in question are compared. Knowing the trajectory of a bullet points you in the direction of its origination. There are also some clues that will help you determine from how far a shot was fired, such as approximate speed on impact and the presence of burnt gunpowder.

A comparison microscope is used to compare the bullets, or marks made on the fired cartridge case by the extractor and firing pin.
