RCBS Single Stage Shell Holder #37 Size

The RCBS Single Stage Shell Holder #37 Size is a precision reloading accessory engineered to align ammunition cases correctly during the reloading process. Built from hardened steel, this shell holder is an essential component for anyone using single-stage or turret presses to reload rifle and handgun ammunition. The #37 size is specifically designed to accommodate cases within that dimensional range, ensuring consistent headspacing and reliable case positioning across multiple reloading cycles.

The shell holder captures 0.125 inch of the case head, which is the critical measurement for maintaining proper SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) headspacing specifications. This precision grip prevents case drift during the pressing stroke, directly translating to more uniform ammunition that performs consistently at the range or in the field. The hardened steel construction resists wear from repeated use and provides the rigidity necessary to maintain alignment even under the pressures of reloading operations. Shell holders are sized to fit specific case head dimensions, making the #37 designation essential when ordering—using the correct size is non-negotiable for safe, accurate reloading.

Reloaders who prioritize ammunition consistency and safety rely on proper case alignment during every stage of the reloading process. Whether you're preparing match-grade rifle rounds, practice pistol ammunition, or specialty hunting loads, the correct shell holder is foundational to your setup. RCBS shell holders are industry standard in single-stage reloading, widely used by competitive shooters, precision rifle enthusiasts, and handloaders who demand repeatability. This #37 size fits cases within that specification range and integrates seamlessly into any RCBS or compatible single-stage or turret press system.
