Product Description The RCBS Full Length Die Set for .338 Weatherby RPM is a precision 2-die rifle reloading set designed for bottleneck cases. It includes a Full-Length Sizer Die with an expander-decapping unit to size the case to SAAMI minimum cartridge dimensions, remove spent primers, and expand the neck for consistent bullet seating. The included Seater Die uses a bullet seater plug and features a built-in roll crimper to help secure the bullet during seating. Integrated venting helps reduce the chance of case damage from trapped air and excessive lubricant, while maintaining minimum headspace tolerances during full-length sizing.
