    For the expert reloaders out there: Is it possible to use 9mm dies to load 38 super? I read a while back about this--not sure if it was here on glock talk or some other forum. Please advise. Any insight would be greatly appreciated. Thanks in advance.

    Not 9mm Luger to my knowledge. You might however, be able to use 9X23mm dies as it is very similar to the .38 Super. Don't quote me on that though. ;)

    That got me curious so I had to try it.
    A .38 Super case run through 9mm dies (backed out that 4mm) delivered a normal LOOKING .38 Super dummy round. It would not gauge, though. I did not have a .38 gun handy to see if it would chamber in a stock barrel.

    Super is .384" straight; 9mm is .380"-.391" tapered. Apparently the Super case was not sized down enough except right at the mouth.

    I size 38super cases by accident regularly. But it's not easy and it's not right. Get a new sizing die. THe crimp and seating die will work depending on manufacture. Hornady uses the same die for 9mm/380 and 38Super for seating.

    Definitely different. They use a different shell holder, too. Although I have used 9mm dies to load up used 38 Super cases to shoot in a 9x23 Winchester; light loads only.

    No. The 9mm is a tapered case and the .38 Super is a straight walled case.

    You can use the same shell holder though.

    It appears that Hornady does indeed use the same shell holder (a #8).

    I have RCBS dies and it is the same shell holder for 9x19 (luger/parabellum) for 9x21 and 9x23 Winchester (#16), but RCBS uses shell holder #39 for 38 Super.

    So I guess the answer is, it depends on what brand of shell holder you use.

    Thank You All.....great info. I guess it's best to just spend the money on a new set of dies for the 38 super.

    I use the same shell plate for both. All I have to do is switch the tool head and I'm ready to go.
