The Neck/Shoulder Sizing Bushings by Short Action Customs are designed for precise adjustment of neck and shoulder sizing in their Modular Sizing Dies.
Made from 17-4 H900 stainless steel, these bushings feature a new internal geometry that reduces neck runout and improves loaded cartridge concentricity.
With a diameter of .290 inches, these 6.5mm Creedmoor sizing bushings have a highly polished interior and exterior finish due to specialized heat treatment.
