RCBS Single Stage Shell Holder #38 Size

The RCBS Single Stage Shell Holder #38 Size is a precision reloading component engineered to securely position ammunition casings during the firing pin and die setup process in single-stage and turret press systems. Built from hardened steel, this shell holder is purpose-designed to align case heads with reloading dies with the repeatability demanded by precision ammunition reloading, whether for rifle or handgun calibers that require #38 sizing.

Shell holders work by capturing exactly 0.125 inch of the case head, establishing consistent headspacing that conforms to SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) standards. This standardized engagement depth ensures that every round pressed achieves uniform cartridge dimensions critical for reliable feeding, chambering, and safe pressure performance. The hardened steel construction resists wear and deformation even under repeated reloading cycles, maintaining dimensional accuracy across hundreds of rounds. The #38 sizing accommodates specific cartridge families, so confirming the correct shell holder number for your caliber before purchase is essential—each RCBS shell holder is sized for particular case-head diameters and cannot be substituted across different cartridge types.

Handloaders and ammunition reloaders who demand consistency and repeatability rely on RCBS shell holders as a foundational component of their press setup. Whether preparing match-grade rifle ammunition, developing handgun loads for competition, or maintaining a supply of reliable practice rounds, proper case alignment through a correctly-sized shell holder is non-negotiable. The compact design (approximately 2 x 0.6 x 3.1 inches, weighing just 0.05 lbs) fits seamlessly into any single-stage or turret press without interference, making shell holder changes quick and straightforward during caliber transitions.

RCBS has established itself as a trusted manufacturer in the reloading component market, known for producing equipment and accessories that prioritize accuracy and durability. This shell holder represents that commitment—a small but critical part of the reloading system that directly influences cartridge quality and consistency.
