    1. ballistics - riffle and handgun bullets can be matched to the gun by matching markings on the bullet with the riflings of the gun. This can be done with shotguns too if they have a rifled barrel. A lot of shotgun barrels don't.

    2. Powder residue - can determine distance the gun from fired if close range. Powder residue is also left on the shooter (to a certain extent) if shooter is found soon after firing the gun.

    3. Approximate location of shooter - by determining distance and angle at point of entry in target.

    4. Legal owner of gun - by tracing gun records. However, stolen guns, etc... makes it difficult at times but can still provide leads.

    Hope this helps a little.

    Excellent Question! Let's see. Striations on slug and casing. Chemical match on transferred accelerant(powder). Serial number. Hammer mark on casing. Fingerprints.

    hmm...GSR (gunshot residue), fingerprints, the bullets used on the gun - different bullets/calibers for different guns and apparently guns have their own unique markings they leave on bullets kinda like fingerprints

    slugs, shell casings, prints on the gun, burns from the muzzle flash maybe showing where it was fired.

    i don't know anything about this.
