How Do Striations Form On A Bullet - Web striation markings are created by the rifling in the barrel of a firearm, which imparts a spin to the bullet as it travels down the barrel. This analysis can provide crucial evidence linking a specific firearm to a crime scene or connecting multiple crime scenes to a single weapon. When a bullet is fired it rubs against the inside of the firearm’s barrel and picks up an imprint of the barrel’s unique striations. Web these striations are imparted on bullets as they squeeze through the spiral windings, called rifling, down a gun barrel. However, frequently, no gun is recovered, or a bullet fragment is too small or mangled to observe adequate striations. Web the process involves carefully examining the bullet under a microscope and comparing its striations with a known database of firearms. The grooves in the rifling cause small scratches on the surface of the bullet as it passes by, creating a distinct pattern of striations. Web with bullets, this involves matching the striations on a bullet caused by its passage through the barrel of a gun with marks on test bullets fired through the barrel of a gun found in the possession of a suspect.
