Forget the FCD and separate the seating and crimping into two operations. Seating, then crimping allow you to control both steps better. A plain taper crimp die should be used for semi-autos that headspace on the case mouth, and you aren't actually crimping, just removing any flare in the case mouth for reliable chambering. Try this; load a bullet as usual, seat a bullet but do not crimp. Check how tight the bullet is in the case. If the bullet is tight (thumb pressure or pushing against the bench doesn't move it) all the previous steps are correct...
I use the 4th hole in my turret for taper crimping/mouth straightening; Redding taper crimp die.
