    I don't load many .357 Magnums, but it is commonly known that you can use the same set of dies for loading .38 Specials. (Which I do load a lot of.)

    A moment ago I was working on getting some 9mm brass cleaned up and ready for priming, when the thought occurred to me -- can you use your 9mm dies to load .380 with? Anyone out there tried this? Any reason not to do it? Thanks! :D

    thats a good question. I'm glad you asked instead of me in case someone says its ......well you know.:) But really, i have been thinking about asking but decided to order a set of 380 dies yesterday.

    No you can't. The cases are a different size by a few thousanths. Even the shellholder is different. The only thing the same is primer and bullet (diameter that is).

    Many thanks for the prompt, helpful replies.

    Though the 9mm casings are obviously longer than .380, I would have guessed that the casings were otherwise the same size. But whipping out my trusty caliper and measuring them shows the 9mm (at the case mouth) has an OD of .374 and the .380 OD is .371. That's good to know. Thanks again! :D

    The 9mm case is tapered .011" and the .380 is tapered .001".

    SO, the base of a 9mm case is .391" and a .380 base is only .374".

    Quite a differance.

    Though I have no experience, I believe that normal .45ACP dies can be used to reload .460 Rowland, too.

    (not related to OP's question, but another "dual purpose" die for the list...)

    No, 9mm and .380 take different dies.
    You can use .38 Special dies to resize 9mm, but it overworks the brass. I haven't tried it for .380; that might actually work.

    I'm gonna try using 9mm dies to load .38 S&W this weekend. (next on the list is .30 Carbine dies + a .223 shellholder to reload 7.62 Nagant Revolver)

    .38 S&W uses a larger sizer than .38 Spl, so you really will be squeezing the snot out of them with a 9MM sizer.

    But I won't be squeezing the snot out of the case heads; that's the important end :) Since the 9mm dies are tapered, I can adjust the amount of sizing by raising the die a bit. I don't think it'll be necessary tho' because .38 S&W's are a little shorter than 9mm.

    If it doesn't work, I'll buy a set of .38 S&W dies. (or 9mm Makarov... ;))

    According to Lyman, their die set 7680116 loads both 38 Super and .38 S&W.

    Interesting. I will have to mic my .38 Super & .38 S&W sizer dies when I get home. I just don't see my .38 S&W die sizing .38 Super enough, especially since I had to get a Lee U die for .38 Super, but I might be surprised. Might as well mic my two .38/.357 sizers as well.

    I use .45 LC for .45 acp. No bulge when using lead bullets, greater powder capacity, less stress on the brass. Fits perfectly in the chamber.

    DO tell us more.

    The only .45 ACP's I know of have .45 ACP chamber shoulders, and .45 Colt won't fit in them all the way.

    Revolvers made for .45 ACP in moon clips won't work with .45 Colt cases because of the same headspace shoulder in the chambers.

    Plus if you trim them short enough to fit, the .060" rim of a .45 Colt is way too thin to headspace properly in a .45 ACP revolver with .089" rim clearance for clips & Auto-Rim cartridges.

    .38 Spl sizer - .371

    .38 S&W sizer - .376

    .38 Super sizer - .375

    .38 Super sizer "U" die - .373

    ------------------------------------------------------------

    .380 sizer - .371 to .365

    9MM sizer - .379 to .371

    Of course other dies will be a bit different due to manufacturing tolerances, but this gives us a good idea of how they match up.

    Certainly looks feasible.

    Looks doable. Neck sizing with a 9MM sizer.

    I use the 38 Auto dies to reload 9mm Largo. There are slight differences but I have no trouble with feeding or going into battery or ignition. Of course I use load data for 9mm Largo, not other cartridges.

    Sorry, I was in a hurry. I am refering to using the .45LC resizing die for .45 acp.

    If you are getting enough neck tension doing it, it will work, but .45 Colt sizers are definitely bigger than .45 ACP sizers. My .45 Colt sizer is bigger than my biggest .45 ACP sizer, and my biggest .45 sizer won't work with thin Remington brass, so it certainly wouldn't work with the Colt sizer.

    I've had trouble before with thin (Remington?) .45LC brass and .451 bullets, so I used a .30-06 die backed way out to "neck size" the cases (same as using a .45 ACP die) They sort of looked like .44-40 cartridges when I was done. It worked OK but seemed kind of kludgy, even for me.

    The .45 ACP case is slightly tapered from .476" at the head to .473" at the mouth.

    The .45 Colt case is a straight .480" all the way.

    Sounds like a good way to have bullet set-back pressure excursions in an auto-loader to me.
