You might actually turn out to be perfectly good to go with that setup. The only whole die addition that comes to mind to suggest is a Redding Profile Crimp die for the .357 Magnum. For a full power revolver round that needs a good roll crimp to prevent bullet back-out (especially light weight revolvers), this is a good choice. these dies constrain the case within the radial elastic limit of the brass to eliminate the development of a below-crimp bulge during heavy crimping. While the Lee Carbide Factory Crimp Die will iron out such a bulge, it always springs back a little, a problem you don't have if it never forms in the first place.
