I just picked up a 380 shooter and haven't reloaded for that particular round.

Can .380 ammo be reloaded using 9mm dies?

I know that the 38 Special/.357 and the 40/10mm can be reloaded on the same set of dies but wondered about the .380/9mm set up.

Any input would be great!!!!

It looks like Hornady list their dies to be able to be set for both. Lee doesn't have descriptions on line. Make a dummy round and try it worst it'll cost is a shell and a bullet.

No. The 9mm is a tapered case that is about .020" larger at the base than the straight sided .380.

The 9mm Luger is a tapered cartridge. The.380ACP does not share the taper or the diameter. You'll need a .380 die set.

Frequently, dies from 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.

45 Colt - 454 Casull *
44 Special - 44 Magnum
38 Special - 357 Magnum
357 Magnum - 357 Maximum
38 Super - 9 mm Largo
44 Russian - 44 Special
40 Smith & Wesson - 10 mm - 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.

well actually in a pinch i've done it, but i ain't gonna say how, cause of the constructive criticism that would evolve

All my manuals list the 380 as straight .373". While the 9mm is in fact tapered with a mouth of .380 base of .394. However when you run it in a carbide sizer die it comes out pretty darn straight.

Thanks for the Interchange link. I didn't find that last night. It sounds like it may not size the brass.
