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.
