RCBS X Die Full Length Die Set .338 Win Mag - 39312

Full length die set for .338 Winchester Magnum rifle reloading that includes an X Die Sizer and Standard Seater Die. The X Die features a patented mandrel design that eliminates case mouth growth, requiring only one initial trim of .020 inch off maximum length rather than repeated trimming with each reload. This set is designed for shooters who want to standardize cases and reduce maintenance in their reloading process.
