RCBS 31401 Full-Length Die Set for 7mm WSM

The RCBS 31401 Full-Length Die Set is designed for reloading 7mm WSM bottleneck cartridge cases. This two-die set includes a Full-Length Sizer Die with an Expander-Decapping Unit and a Seater Die with a Bullet Seater Plug. Together, these dies provide the essential sizing, depriming, neck expanding, bullet seating, and crimping functions needed for a consistent reloading process. The set is suitable for reloaders who want reliable case preparation and controlled bullet seating for 7mm WSM ammunition.

The Full-Length Sizer Die returns cases to SAAMI minimum cartridge dimensions while sizing the outside of the case, removing the spent primer, and expanding the neck to accept a new bullet. Its vented design helps reduce the risk of case damage caused by trapped air or excessive lubricant. Headspace is maintained within minimum tolerances to help prevent unwanted changes to case body length during full-length sizing, supporting dependable chamber fit and consistent case performance.

The included Seater Die features a built-in roll crimper that secures the bullet during the seating operation. This integrated design helps streamline the reloading process while providing controlled bullet placement and a firm crimp when appropriate for the load. Built for the RCBS Full-Length die series, the 31401 set offers durable construction and practical functionality for 7mm WSM handloading applications. Follow all applicable reloading data, equipment instructions, and safe handling procedures when using this die set.
