Does the ballistic evidence merely confirm that the ammunition is the same, or does it confirm that the same weapon is being used?

Good question. My recollection is that the bullet fragments that are recovered from the victims have "fingerprints" on them from the barrel they have been shot from. I have assumed that each bullet has been verified as having been shot from the same barrel of the same gun whenever a sniper shooting is confirmed. But I could be wrong.

Calling in the reinforcements!
