Not at all. Even the best matches of the bullets, lands and grooves rifling patterns, aren't fully reliable. Shell casings give little clue unless there is an anomaly with the firing pin, chamber, or ejector. That or the sizing/shape of the case is custom.
Don't believe anything on CSI or other Hollywood—most of those writers don't know a Sig from a Paintball gun.
