RCBS 20515 3-DIE CARBIDE TAPER CRIMP DIE SET 9MM LUGER/9X21/9X23MM

RCBS pioneered and developed 3-Die Sets for straight-wall 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 taper crimps.A shell holder is not included with this die set.
