RCBS 30 M1 Carbine Carbide 3-Die Set

RCBS pioneered and developed 3-Die Sets for straight-wall rifle and pistol cases. The 30 M1 Carbine 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. Mfg: Rcbs
