Shovel it is not necessary to crimp .223 for most AR platform rifles. A lot of my friends shoot my reloads, and rave about how accurate they shoot. Not one is crimped. If you have the Lee Deluxe Die set your bullet seater is the Dead Length Seating Die. It does not crimp anyway.

Oh and shooting an AR you will not be using the Collet die. You will have to F/L Resize every case.
