RCBS X Die Small Base Sizer Die .308 Win - 39259

This RCBS X Die is a full-length sizer die designed for .308 Winchester bottleneck cases with a small base configuration. The patented design features a specially designed mandrel with expander ball and decapping pin that reduces case mouth growth, eliminating the need for repeated trimming after an initial standardization trim. The die minimizes case length growth during the sizing process, making it ideal for shooters who want to reduce maintenance in their reloading workflow.
