RCBS Steel 3-Die Set with Roll Crimp – 50 Action Express

Description

RCBS® pioneered and developed 3-Die Sets for pistol cases. The Steel Sizer Die sizes the case and de-primes (steel sizer dies require case lube). The Expander Die expands the case to the proper diameter to accept the bullet, and it imparts case mouth flare/bell for bullet feeding. The Seater Die seats the bullet and taper crimps.
