RCBS Full Length Die Set for .357 Sig Cartridge Reloading

357 SIG GP-A

The RCBS Full Length Die Set for .357 Sig provides precision and reliability for reloading bottleneck cases. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a built-in bullet seater plug and roll crimper, ensuring a seamless reloading process. The Full-Length Sizer Die brings cases to SAAMI minimum dimensions by resizing the exterior of the case, de-primeing, and expanding the case neck to accept bullets efficiently. It features venting to prevent trapped air and excessive lubricant build-up, which helps avoid case damage and ensures consistent sizing.
The die maintains strict headspace tolerances, preventing changes to case body length during full-length resizing, which contributes to uniform reloads and reliable chambering. The included Seater Die simplifies bullet seating by combining seating and crimping functions into a single step, reducing handling and ensuring consistent pressure on each cartridge. This setup is ideal for reloaders seeking precision in .357 Sig cartridge production, whether for target shooting or personal defense.
Constructed without carbide components, the RCBS Full Length Die Set is durable and easy to maintain. Its dimensions of approximately 1.75 inches in width, 4.55 inches in length, and 6.00 inches in height make it compatible with standard reloading presses. Designed specifically for bottleneck cases, this die set enhances your reloading workflow by delivering consistency, accuracy, and efficiency in every cartridge produced.
