RCBS - X-Die Full Length Sizer Die 308 Winchester - 37809

Overview

The RCBS X-Die Full Length Sizer Die in .308 Winchester is a precision steel reloading die engineered to resize the cartridge body and decap in a single operation. Designed to accommodate ammunition used across bolt-action, pump, slide, automatic, semi-automatic, and lever-action rifles, this die features a proprietary mandrel design that contacts the case mouth during sizing to control case growth. After an initial trim of .020 inches, the X-Die eliminates the need for repeated trimming while preventing the case neck wall from thickening as the case length is pushed back. Cases sized in the X-Die stabilize below the maximum case length with consistent accuracy and extended case life. The unit uses regular decapping pins and requires a standard shellholder, which is sold separately.
