RCBS 25 WSSM Full Length Die Set for Reloading Bottleneck Cartridges

25 WSSM GP-A

The RCBS 12401 Full Length Die Set is designed for precise reloading of the .25 Winchester Super Short Magnum (WSSM) cartridge. This two-die set includes a full-length sizer die and a seater die with a built-in bullet seater plug, facilitating efficient and accurate reloading for enthusiasts and professionals alike. The full-length sizer die ensures that cases are resized to SAAMI minimum dimensions, which is essential for consistent chamber fit and reliable firing. It sizes the outside of the case, de-primes spent primers, and expands the case neck to accept the new bullet, all while venting to prevent trapped air and excessive lubricant buildup. Headspace is maintained within tight tolerances to avoid altering case body length during resizing, ensuring uniformity across reloads. The seater die features a built-in roll crimper, allowing seamless bullet seating and crimping in a single operation, which enhances precision and reduces reloading time. Compactly designed, the set measures approximately 1.75 inches by 4.60 inches by 6.05 inches, making it a practical addition to any reloading bench. Crafted for durability and accuracy, this set offers reliable performance for those reloading bottleneck cases in the .25 WSSM caliber. Whether you are developing custom loads or maintaining a consistent cartridge for hunting or target shooting, the RCBS Full Length Die Set provides the necessary tools to achieve professional results with every reload.
