RCBS Single Stage Shell Holder #39 Size

The RCBS Single Stage Shell Holder #39 Size is a critical component for handloaders seeking precision and consistency in their reloading process. Designed specifically for use with single-stage and turret presses, this shell holder ensures that the cartridge case is perfectly aligned with the reloading die. Proper alignment is paramount to maintaining the structural integrity of the brass and ensuring that every round produced meets strict dimensional tolerances for reliable chambering and ignition.

Constructed from high-grade hardened steel, the RCBS Single Stage Shell Holder #39 Size is built to withstand the significant pressures exerted during the resizing and decapping stages. The use of hardened steel prevents the shell holder from deforming or wearing down over time, which is essential for maintaining a uniform height and grip on the case head. This durability makes it a staple for high-volume reloaders who require equipment that performs consistently through thousands of cycles.

A key technical specification of this shell holder is its ability to capture exactly 0.125 inches of the case head. This precise measurement is engineered to meet SAAMI (Sporting Arms and Ammunition Manufacturers' Institute) headspacing requirements. By securing the case at this specific depth, the RCBS Single Stage Shell Holder #39 Size helps eliminate variations that can lead to headspace issues, thereby improving the safety and accuracy of your finished ammunition.

Whether you are performing a technical review of your reloading bench or looking to buy a replacement for a worn component, these specifications highlight why RCBS remains a leader in the industry. The #39 size is tailored for specific case head dimensions, providing a secure fit that prevents the case from slipping or tilting during the stroke. Investing in dedicated shell holders for each caliber ensures that your reloading setup remains efficient and your output stays within professional-grade specifications.
