RCBS AR Series Taper Crimp Seater Die 223 Remington, 5.56x45mm NATO

The RCBS AR Series die set is a must for any progressive reloader. The taper crimp seating die is helpful as it is bit a more forgiving die for crimping cases that have variable case lengths helping to reduce the number of bulges and buckled shoulders when crimping in bullets with a cannelure.
