RCBS X Die Full Length Die Set .300 Wby Mag - 39212

This full length die set for .300 Weatherby Magnum includes an X Die Sizer and Standard Seater Die, designed to eliminate the need for repeated case trimming after an initial trim. The patented X Die features a specially designed mandrel with expander ball and decapping pin that reduces case mouth growth rather than shortening case length. Compatible with .300 Weatherby Magnum rifle cartridges.
