    I got a hold of a box of Fabrica Militar De Cartuchos .San Lorenzo. Cartuchos Calibre 11.25 mm.

    I was told this is .45acp by the man.

    The headstamp is

    F.M.C. "S L" on the top half,

    ll 1954 ll on the bottom half

    Measuring the case width, it is .470
    Overall length is 1.26
    Diameter at the base of the bullet, right at the case is .435-.436

    It looks like a .45acp, but I really don't want to have a kaboom from firing something through my 1911 that wasn't intended.

    Any info? Is it ok to fire, or should I set it on the shelf and look at it?

    Just from it being from Mexico and 1954, I wouldn't fire it.

    That said, 11.25mm = ~.45, so yes, that plus the overall length says it's .45acp.

    I forgot to mention, it's from Argentina

    Yes, it's Argentine, and was MADE for a 1911A1, the Sistema. Probably corrosive, so clean well. I would keep the box and 2 rounds, see if the rest shoots OK.

    If your intention is just to fire it, a better plan would be to swap it for an equal amount of modern .45acp ammo to someone who has an Argentine .45 from the mid 1950s and might want it for collecting. Hint, hint.

    Senior Oro, would you happen to have an Argentine .45 from the mid 50's???
