reloading 380 with 9mm dies

peddler
I have just purchased a Beretta 84 in 380acp, I have not tried but does anyone know if it might be possible to reload the 380 using 9mm dies in the Dillon SDB press? I reload 32 SW short with the Dillon SDB and 32 SW long dies. Thanks for any info.

    Well, I haven't tried it but HAVE loaded 9mm largo (9X23) with 9mm dies... same diameter bullet; so I don't see as it would be an issue IF the seating stem comes down deep enough to seat your selected bullet.

    The 380 case is shorter by .074

    Both use the same diameter bullets, but that is where the similarity ends.

    9mm Luger is a tapered case, with a relatively thick wall. OD .381" at the mouth

    380 is a straight walled case with a relatively thin wall. OD .372" at the mouth

    The twist to this comes in that Dillon makes no provision for the 9 luger being tapered, and uses a straight sizing ring. I expect it will not adequately size the cases to hold most bullets, you might get away with this using slightly oversized lead bullets.

    I have tried it using properly made 9mm dies and it just didn't work.

    length isn't the biggest problem.

    You are correct. It is one of a whole series.

    Simply said won't work. You will need to invest in some 380 ACP dies.

    There is also a difference size shell holder as the rim is a different dimension.

    Or get a Lee Factory Crimp die for the 380.
