If you have a single stage press it is most convenient to add the Hornady Lock-n-Load bushing (on most LEE, RCBS, etc.) and use the quick change feature: one quick twist to go from die to die. I recommend the 4 die Lee sets for 380acp and 9mm because the FCD is also a 2nd carbide sizing ring that helps virtually insure your reloads will chamber, providing you are within correct OAL dimensions. Quite often the case tension on the bullet can reduce the need for a taper crimp to a very slight one. The extra costs are well worth the time saved and convenience: the Hornady lock rings are also great for your seating dies, as well. Lee lock rings use a rubber O-ring and can slip.
