RCBS 7x57 Mauser Full Length Die Set for Reloading Bottleneck Cartridges

7X57MM MAUSER GP-A

The RCBS 13801 Full Length Die Set is designed for precise reloading of 7x57 Mauser cartridges, ensuring reliable and consistent firearm performance. This two-die set includes a Full-Length Sizer Die with an expander-depriming unit and a seater die with a built-in bullet seater plug and roll crimper. The Full-Length Sizer Die brings your cases to SAAMI minimum dimensions by resizing the outside of the case, removing the spent primer, and expanding the neck to accept new bullets. It features a venting system to prevent trapped air and excessive lubricant buildup, which can cause case damage or resizing issues. The die maintains minimal headspace tolerances, avoiding changes to case body length during full-length resizing, thus aiding in maintaining consistent chamber fit and accuracy.

The included Seater Die is designed to seat bullets accurately and securely. Its built-in roll crimper ensures that bullets are crimped at the same time as they are seated, providing a tight, reliable fit for consistent chambering and ignition. This die set is ideal for reloaders seeking precision and durability without carbide components, making it suitable for a variety of reloading conditions. With dimensions measuring approximately 1.85 inches by 4.50 inches by 6.00 inches, this set is compact and easy to handle, fitting seamlessly into your reloading bench.
