    Gunny, does the extractor also leave identifiable tool marks on the brass?

    Yes the extractor does. The ejector, chamber, breach face and firing pin aperture also leaves marks.

    Probably doesn't come up in crime all that often, but I'd wager my oft reloaded and shot in many guns range brass would give a tech fits, other than the primer of course.

    I can guess that a computer system is used to scan, catalogue, and compare all the data from brass and bullets. Why? --- there seem to be thousands of data points to check and compare. More so than the human eye can sift through in a reasonable amount of study time. Computer scanning also is the basis of a "library" of stored crime information which can be shared over the internet among PD's and the Feds. You can also amuse yourself with "Primer Pictures" if you have the time. :)

    I thought the first primer had “pin-wipe” from opening prematurely...

    Then the picture looked to me like a baboon rather than a dog... but it is animal-looking for sure!

    Cool images :thumbup:.
    Stay safe!

    All look like over-enlarged prints osonograms by excited new parents--which would be my failure of imagination.
