The Redding Reloading Equipment is a precision-engineered neck sizing bushing designed for reloading applications. Constructed from heat-treated steel, this bushing offers enhanced durability and longevity, ensuring consistent performance under rigorous conditions. With a precise internal diameter of 0.316 inches, it is specifically tailored for 7mm cartridges, providing optimal neck tension and alignment during the reloading process. The heat treatment process enhances the bushing's resistance to wear and deformation, maintaining its dimensional integrity over extended use. This component is an essential tool for reloaders seeking to achieve superior accuracy and consistency in their ammunition. The heat-treated steel features hand-polished sizing diameters with a surface hardness of RC 60-62, designed to minimize the effort required for sizing Redding neck sizing bushings are fully compatible with all redding bushing dies and seamlessly interchangeable with Wilson-style bushings, ensuring versatile and precise reloading performance
