Last year I started into reloading and was able to acquire a RCBS RC II press, scale, 2 die sets and misc accessories for a great price. I promptly started feeding my 9mm and 38Spl with new Lee dies. Later on I got a .357 and started loading for it as well.
One of the die sets that came with the deal for the press was an older steel 3pc RCBS 357 SWC set. I have been using the Lee sizing die for both calibers and recently I received an additional steel .357 RN set (that also included a SWC seating stem and crimp die). So I am set for expanding and seating, sizing is still my weak point.
I want to keep the die sets separate due to reloading space resulting in my search for a RCBS Carbide sizing die.
I can if course keep using the Lee die, or go to the interweb and click myself a new RCBS sizing die but where's the fun in that. The die doesn't have to be NIB used and dirty but usable is fine and doesn't need the de-priming pin assembly as the older set has the primer pin on the expanding die.
