RCBS 9231 Single Stage Shell Holder #31 Multi-Caliber

The RCBS 9231 Single Stage Shell Holder #31 is a precision machined shell holder for RCBS single-stage and turret reloading presses. Built from hardened steel with a silver finish, this Size #31 holder is sized to grip roughly 0.125 inch of the case head for proper SAAMI headspacing during resizing and decapping.

Classified as Multi-Caliber, shell holder #31 covers a tight group of large and obsolescent cartridges that share a common case-head dimension. It fits the .400 Jeffery (also known as 450 x 400 Express 3"), the 45-75 Winchester, the 50-70 U.S. Government, and the .50-90 Sharps (2-1/2"). As with the rest of the RCBS lineup, the numbering is unique to RCBS and is not interchangeable with shell holders from other makers.

Each holder is precision sized to its specific case head so the cartridge is squared with the reloading die, supporting consistent shoulder bump and overall length during handloading. Whether you are loading for a vintage Sharps single-shot or a modern 400 Jeffery dangerous-game rifle, this RCBS #31 shell holder delivers the firm, repeatable case grip serious reloaders expect from the brand.
