RCBS Single Stage Shell Holder #46 Size

The RCBS Single Stage Shell Holder #46 Size is a hardened steel reloading component designed to securely hold cartridge cases during the reloading process. Built to exacting tolerances, this shell holder aligns cases precisely with reloading dies in single-stage and turret presses, ensuring consistent headspacing and case positioning critical to safe, accurate ammunition production.

Each shell holder captures 0.125 inch of the case head, which is the standard measurement that establishes proper SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) headspacing. The Size #46 designation indicates this holder is caliber-specific and sized to fit the case head dimensions of its intended cartridge. The hardened steel construction resists wear during repeated loading cycles, maintaining accuracy and reliability across hundreds of reloading sessions. The compact design (2.3 x 0.55 x 2.9 inches) allows easy installation and removal from both single-stage and turret press ram assemblies.

This shell holder is essential for reloaders who demand precision and consistency. Whether you're a rifle cartridge specialist optimizing for accuracy, a pistol ammunition producer managing volume, or a competitor preparing match-grade loads, proper case alignment through a correctly sized shell holder directly impacts powder charge consistency, bullet seating depth, and overall load uniformity. RCBS shell holders are organized by size number; selecting the correct size for your specific cartridge is critical—an incorrectly sized holder will result in misalignment and unsafe loads.

RCBS has been the benchmark in reloading equipment since 1956, and their shell holders remain the industry standard because they combine precision engineering with straightforward reliability. The #46 size fits a specific set of cartridges; verify your case specifications against the RCBS shell holder sizing chart to ensure compatibility before purchase.
