RCBS 20415 Carbine 3-Die Set Group B .380 ACP

RCBS's Carbide 3-Die Set features a 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.
