RCBS 19112 3-Die Carbine Roll Crimp Set Group B 45 Colt (LC)

RCBS's 3-Die Carbide Sets is for straight-wall rifle and pistol cases. The Carbide Sizer Die sizes the case and de-primes (the carbide sizer ring eliminates the need to lubricate). Its 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 roll crimps.
