Now that I have a 550, I’m still waiting for conversions and a few other parts before I can get started playing around. Question: I have Lee 3 die sets for 380, 40, and 38/357. I’m guessing the resizing/depriming die and bullet seating die are all I will mount in the toolhead? The powder die/funnel is part of the conversion, right? That’s 3/4 toolhead holes used. Does the 4th just remain unused in absence of factory crimp?
