RCBS Single Stage Shell Holder #12 Size

The RCBS Single Stage Shell Holder #12 Size is a precision reloading component engineered to hold and align ammunition cases during the reloading process. Built from hardened steel, this shell holder is designed specifically for #12-size case heads and works with single-stage and turret presses to ensure proper headspacing according to SAAMI specifications.

The holder captures exactly 0.125 inch of the case head, a critical dimension for maintaining consistent headspace tolerances across your reloaded ammunition. This precise capture depth ensures the case sits at the correct distance from the reloading die, which directly affects cartridge performance, chamber fit, and firearm safety. The hardened steel construction resists wear and deformation even under repeated use in high-volume reloading operations, maintaining dimensional consistency shot after shot.

Handloaders who work with cartridges requiring #12-size shell holders—such as .222 Remington, .22 Hornet, and similar compact rifle rounds—depend on this component to produce ammunition that chambers reliably and performs consistently. Whether you're a precision rifle shooter optimizing load development, a competitive marksman fine-tuning ammunition for accuracy competitions, or a reloader processing large batches of rifle brass, proper case alignment through a quality shell holder is fundamental to reloading success. RCBS shell holders are industry-standard components trusted across reloading presses from multiple manufacturers.
