RCBS 45 ACP Carbide Sizer and Seater Die Pair

Updated September 23, 2026

Two RCBS dies for the 45 ACP in the gray RCBS storage box that is labeled as a three die carbide taper crimp set, part number 20415 style packaging, with the end label calling for shell holder 03. Read this before bidding. Only two of the three dies are present. The box holds the carbide sizing and decapping die, stamped 45 CARBIDE, and a 45 ACP die stamped 45 ACP. Two of the four cradles in the box are empty. The printed RCBS reloading dies instruction booklet is included. The carbide sizing die is the valuable half of the pair. A carbide ring sizes straight wall 45 ACP brass with no case lube, which on a high volume pistol round saves a lubing step and a cleaning step on every batch. The missing die can still be bought separately from RCBS as a single die. Dies are clean with light surface oil and normal handling marks, threads and lock rings are intact and no rust or galling is visible in the photos. Condition is very good. Estimated Value: $30 to $50 based on comparable recent sales. Sold as-is. Photos are the most accurate description of this lot. Written descriptions are a guide only and may contain errors.
