RCBS X Die Small Base Die Set .223 Rem - 38862

This RCBS X Die set is designed for .223 Remington rifle reloading and features a patented mandrel design that reduces case mouth growth during sizing, eliminating the need for repeated case trimming after an initial standardization trim. The set includes an expander ball and decapping pin integrated into the mandrel for efficient case preparation. Small base sizing provides reliable chambering in AR-platform and other tight-tolerance rifles.
