RCBS 3-Die Carbide Taper Crimp Set Features The RCBS 3-Die Carbide Taper Crimp Set pioneers the three-die approach for straight-wall cartridges splitting sizing expanding and seating into dedicated stations for more consistent results. The Carbide Sizer Die resizes the case and removes the spent primer in a single pass and because the sizing ring is carbide reloaders skip the step of lubricating cases before running them through the press. The Expander Die opens the case mouth to the correct diameter for the bullet and imparts a case mouth flare that helps bullets seat straight and true. This combination reduces the chance of bullet deformation or case damage during the reloading process. The Seater Die finishes the job by seating the bullet to the proper depth and applying a taper crimp that holds the bullet securely while maintaining correct cartridge headspacing for reliable feeding and chambering. All RCBS dies in this set are machined to exacting tolerances then hardened and finished to a high standard for long-term durability on the reloading bench. Packaged in RCBS s recognizable green box the set is made in the USA to the company s established quality standards.
