RCBS Full Length Die Set 7mm WSM – Model 31401

The RCBS Full Length Die Set 7mm WSM (Model 31401) is designed for reloading bottleneck cases, offering precision and reliability for serious reloaders. This two-die set includes a full-length sizer die with an expander-decapping unit and a seater die with a bullet seater plug. The full-length sizer die ensures cases meet SAAMI minimum cartridge dimensions, sizing the exterior, de-priming, and expanding the neck for bullet acceptance. Vents in the die prevent case damage from trapped air and excessive lubricant. The seater die features a built-in roll crimper to secure the bullet while seating. Ideal for crafting high-quality ammunition, this set provides consistent headspace tolerances to maintain case body length during resizing.
