    9mm brass the same size as my 380 brass

    I just purchased 1000 pieces of. O central fired .380 brass.
    As I was reloading some I see a bunch with a head stamp of 9mm. These "9mm" pieces of brass were marked 9mm Br.C. S&B
    I know what S&B is but why are they marked 9mm? They are the exact same size as my .380 brass.
    Can these be loaded up and shot in my .380?

    Well, .380 ACP is also called 9mm Short, or (9mm Kurtz in German), so some .380 cases will be found with some sort of "9mm" headstamp.

    In the case of S&B cases, the "Br.C." stands for Browning Court, which is French for "Browning Short."
    So 9mm Br.C. is the same as 9mm Short, or .380 ACP.

    Maybe they are referring to the 9MM Kurz.

    A 9MM MAY expand to .45 but a 45ACP will never shrink to 9MM.

    FWIW, before I bought a few thousand 9x18 brass I would cut down 9x19 brass and use it. No, it's only a close fit, not an ideal fit, and that's why I bought the 9x18 brass. But it works in a pinch with full length sizing die.

    Anyway, My point being...many calibers are 'close enough' to use, but I wouldn't make a habit out of reloading these 'fire formed' cases, just my opinion.

    As for the Kurtz, it's the same case with a different head stamp. https://www.starlinebrass.com/380-auto-brass

    It's amazing what you will find on Google.

    The only thing I have trouble finding is very specific research topics. But paid sources have that.
