RCBS Single Stage Shell Holder #48 .338 Norma Mag

The RCBS Single Stage Shell Holder #48 for .338 Norma Mag is a precision reloading component designed to securely hold rifle cases during the single-stage and turret press reloading process. Built from hardened steel, this shell holder ensures consistent case alignment with reloading dies, a critical requirement for achieving proper case headspacing and producing safe, accurate ammunition. The shell holder captures 0.125 inch of the case head to maintain SAAMI-spec headspace dimensions throughout the reloading cycle.

Shell holder selection is caliber-specific because case head dimensions vary significantly across rifle cartridges. The #48 model is engineered exclusively for .338 Norma Mag—a modern magnum rifle round—meaning it will not function correctly with other case heads, and using an incorrect holder can result in damaged cases or dangerous headspace conditions. The hardened steel construction resists wear from repeated insertion and removal of cases, extending tool life across hundreds of reloading cycles. This shell holder is compatible with RCBS single-stage presses and most turret press models that use standard RCBS shell holder threads.

Reloaders working with .338 Norma Mag ammunition—whether for long-range precision shooting, hunting applications, or handload development—depend on correct shell holder selection to eliminate variables that could affect case integrity or finished round consistency. The RCBS #48 is a foundational component in any .338 Norma Mag reloading setup. Verified compatibility with your specific press model and cartridge is essential before purchase.

RCBS remains the established reference standard for reloading equipment and shell holders across competitive and commercial reloading operations. The shell holder format—a simple, standardized component—has remained largely unchanged for decades, ensuring broad compatibility with a wide range of press designs and user-maintained equipment.
