RCBS 38/357 seater and taper crimp die.

[MOA]

This is a stand alone die made by RCBS for the sole purpose of seating and applying a tapered crimp only.
Does anyone know if it can be used to apply a tapered crimp on a 380 acp cartridge?

Thanks.

I seriously doubt you could get the 380 case far enough into the die to get any kind of crimp on it.

Tazman is correct. Also, they're not even the same size. Look at the cartridge spec/dim in your loading manual.
