I use the Lee carbide 4 die setup for 9mm loading and find that the crimp that the bullet seating die applies is more than adequate for plated or jacketed, so I don't actually use the FCD. I don't know if this would apply to 45 rounds though with the higher? pressures.

I've seen a lot of people say they don't use the FCD for most things when I was doing my initial research into loading.
