RCBS Carbide Roll Crimp 3 Die Set - Group E - Straight Walled Cartridges - .32 S&W Long / H&R Mag / .327 Fed 21412

RCBS pioneered and developed 3-Die Sets 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). 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 roll crimps.
