    ...But I'm gonna ask anyway! :rolleyes:
    Can 9mm Luger dies be used to reload .380 auto?

    Lee Interchangeable dies

    Nohttp://www.leeprecision.com/cgi/faq/index.cgi nterchangeable dies

    Frequently, dies from one caliber may be used to load other calibers. Due to the locations of crimping shoulders, the operation may only work for dies of the shorter caliber to the longer. You may notice a label depicting the shorter die in your set for the longer version of the cartridge, we do this to reduce costs.

    Even though some dies are interchangable, in many cases, different shellholders are necessary. You can see a complete list of shellholders under "Case Preparation" then "Shellholders and Calibers".

    45 Colt - 454 Casull *
    44 Special - 44 Magnum
    38 Special - 357 Magnum
    30-30 Winchester - 30 Remington
    357 Magnum - 357 Maximum
    38 Super - 9mm Largo
    44 Russian - 44 Special
    40 Smith & Wesson - 10mm - 41 Action Express
    32 Smith & Wesson - 32 S&W Long - 32 H&R Magnum **

    *The 45 Colt expander die will also work for the 454 Casull by backing the die out approximately two turns to compensate for the difference in case length.

    **Our dies allow the use of .308 bullets in the 32 H&R Magnum. The other bullet diameter commonly used is .311 and that is the expander that comes with the set. To use .308 bullets, it is necessary to purchase an additional expander and turn it down to .308. This can be done using a drill press and emery cloth or if you buy the additional expander from the factory, we will do it for $10.00.

    I've seen this question before and seem to remember the objection is that the .380 is a straight wall case and the 9mm has a small taper to it, so the consensus was no. But hey, I've been wrong before.

    "9mm Largo"? That can't be a misprint for Luger; that looks like a copy & paste from a equiment catalog......

    Google has, from 9mmlargo.com: "The next year, 1908, the Spanish adopted the Bermann Modelo 1908 as their official sidearm and began manufacturing the round [other sites say it is 9x23mm] with the designation 9mm Largo." I'll be damned! Yuh learn sumthin even when you aren't tryin' to, here.

    No. Not really. It could be done in a pinch, but you really need .380 dies.

    9MM Largo is another caliber all to its self.

    That's a fact Jack. My dad had a Llama 1911 pattern 9mm that was a jam-o-matic all it's life. Until I inherited it and discovered it was Largo, not 9x19.

    Speer, Hornady, and other brands of jacketed .380 ACP bullets are .355", same as 9mm Luger, etc.

    You would use .356" lead or plated bullets in the same calibers though.

    As has been pretty much summed up, the .380 case is more straight-walled and the brass is actually a bit thinner. You could seat and crimp with 9x19 dies, but resizing wouldn't work.

    I have a Star Modelo Super in 9x23, and it actually runs just fine with 9x19. But I do have plenty of correct ammo for it, so that was just for shiggles and gits.

    The 380 case would never resize in 9mm dies because the 9mm cases are tapered to .015 larger at the bottom and 380 is straight. The case mouth might size enough to hold a bullet but I doubt it because the brass is generally thinner too.

    Especially with 380 brass being so hard to find - I'd sure hate to screw up the pieces I've got! :D
