I can tell you from my own experience to spend the money and buy the Redding (or Whidden) FL bushing die with the competition seating die. When I built my Edge, I was on a budget and ordered the standard set of Redding 338 Edge dies. They were about $100 cheaper. As time went on, I added a micrometer top to the seating die and had the standard FL die modified into a bushing die. Now I have about the same money into my dies and still don't have a competition type seating die.
