RCBS 99240 Single Stage Shell Holder #40 for 475 Linebaugh & 480 Ruger Reloading

The RCBS 99240 Single Stage Shell Holder #40 is purpose-built for reloaders working with 475 Linebaugh and 480 Ruger cartridges. If you're setting up to reload these big-bore revolver rounds, you need a shell holder that seats your cases precisely every time—that's where this comes in. The #40 holder captures the specific case head dimensions of these calibers, ensuring proper alignment with your reloading dies and maintaining safe, consistent headspacing for every loaded round.

Made from hardened steel, this holder is engineered to withstand the repetitive stress of single-stage and turret press reloading. The design grips 0.125 inch of the case head, a measurement that keeps your cartridge seated at the correct height relative to your dies. That precision matters when you're loading magnum revolver ammunition—inconsistent headspacing creates safety risks and reload failures. Whether you're working at the bench with a single-stage press or running multiple dies on a turret press, this holder delivers the repeatability serious handloaders demand.

RCBS shell holders are a straightforward consumable part of your reloading setup: pick the right number for your cartridge, install it in your press, and trust it to do the job shift after shift. The #40 is the correct choice for 475 Linebaugh and 480 Ruger loads.
