The RCBS #25 Single Stage Shell Holder is a hardened steel reloading component built to secure 8mm Nambu cartridges during the full-length resize, depriming, or priming process. If you're working with 8mm Nambu on a single-stage or turret press, this shell holder is the mechanical key that locks your case in proper alignment with your dies—something no shortcuts can replace. It captures 0.125 inch of the case head to maintain SAAMI-compliant headspacing, which means consistent, safe ammunition from start to finish.
Reloading for less common calibers like 8mm Nambu can feel like hunting for the right tool. The wrong shell holder doesn't just make the job harder; it introduces sizing and spacing errors that compromise accuracy and safety. The RCBS #25 is purpose-built for this exact cartridge, engineered with the hardened steel durability RCBS is known for, so you're not gambling on fit or alignment every time you pull the handle.
Whether you're a precision reloader working up loads for a Nambu rifle or simply tired of adapting generic tools to a specialty round, this shell holder removes the guesswork. It's a straightforward, proven piece of press equipment—the kind of component that works quietly in the background but makes the entire operation more reliable.
