Firearm Examination: A NIST Scientific Foundation Review

Close up are the grooves turning around leading down the interior of what looks like a tunnel with light at the end and reflecting on the sides.

This is an image of a 35 Remington caliber, microgroove rifled barrel manufactured by the Marlin Firearms Company. It shows a 20 land and groove barrel with a right hand twist. The image was taken with a Nikon D1X camera using f22 and a 1/30 ss. The bore of the barrel was lighted with a standard bore light.

This report reviews the scientific foundations of firearm examination, a forensic technique used to compare the marks on bullets and cartridge cases under a comparison microscope with the those from a suspected firearm used in a crime.
