.380 A.C.P. Dies

[Ky Larry]

Can .380 A.C.P. (9X17) dies be used to reload 9X19 ammo? Are the case walls the same thickness? Thanks.

P.S. I know 9X18 Mak is a different diameter bullet and can't be used in a 9mm Parabellum or .380 A.C.P.

.380 is considerably smaller o.d. than 9mm P and not tapered, case wall is thinner. The .380 sizing die would take 9mm down way smaller than needed and I don't know if the case would even go in the flaring and seating dies.

Thanks,Jim. I was hoping to use the dies interchangibly, like .38 Spl and .357 Mag.

Shell holders are different, too. I sometimes end up with a 380 case mixed in with my 9mm Luger cases (despite diligent efforts to separate the two,) and when one starts through my Lee Loadmaster it always screws things up. The shell plate will push the case into the sizing die, and usually will pull it out, but as it moves to the priming stage the case usually starts to slip (or tip) out of the shell plate, but not until after triggering the primer feed. So I end up with a loose case and a primer ready to feed on the upstroke, which I have to stop and retrieve.

Lee dies for 380 are not very expensive, and include the properly sized Factory Crimp Die which makes for some very reliable ammuniton.
