RCBS X Die Small Base Sizer Die .223 Rem - 38859

The RCBS X Die is a small base sizer die designed for .223 Rem rifle reloading that eliminates the need for repeated case trimming after an initial trim. Its patented mandrel design with expander ball and decapping pin reduces case mouth growth during sizing rather than shortening case length. This die is compatible with standard reloading presses and is ideal for precision rifle reloaders seeking to improve case longevity.
