That's above my pay grade. Hopefully someone else more knowledgeable will take that oneWould i be incorrect to assume that the fl die could be used in place of a redding body die by simply removing the bushing and expander/decapper rod? That would be a big bonus for me incase i end up not liking the fl bushing route and decide to go back to sizing in 2 steps using lee collet neck die and seperate body die.
