Striations are fine, parallel lines or grooves that are left on a bullet when it is fired from a firearm. These markings are created by the unique imperfections and characteristics of the gun's barrel, making each firearm's striations distinct. For forensic analysis, comparing the striations on a bullet found at a crime scene with those from a suspected firearm can help determine if the bullet was fired from that specific gun, thereby linking the weapon to the crime. This process is crucial in criminal investigations and can provide strong evidence in court.

What are striations how are they produced and how are they useful for comparing bullets?

When a bullet is pushed through a rifled barrel, the rifling (lines cut into the inside of the barrel in a spiral) makes scratch marks on the bullet. No two guns make the exact same scratches. It is possible to examine the scratch marks, on two bullets and see if they could have been fired from the same gun. This uses a device called a comparison microscope.

Can you trace a bullet back to its gun?

Yes, forensics experts can use a process called ballistics analysis to match a fired bullet to the gun that fired it. This involves examining unique markings left on the bullet by the barrel of the gun, such as striations or rifling marks. By comparing these markings with test-fired bullets from a suspected gun, investigators can determine if there is a match.
