You don't need the factory crimp die. .380 ACP is a semi-auto round, it needs a taper crimp, not a roll crimp. The factory crimp die is a sort of "belt-and-suspenders" device, but the third die in the 3-die set also applies a taper crimp as it seats the bullet. Get that die properly adjusted and you're good to go.
