Most reloaders begin their collection of Bench Rest dies with full length sizers due to their maximum flexibility. These dies size the case neck and body, adjust the shoulder to set headspace (length), deprime and expand the case neck. They are machined by hand using one-piece reamers. The unique elevated "E-Z" out expander ball system distinguishes this sizing die. Resizes the case neck, shoulder and body, performs depriming and expands the case neck for optimal cartridge alignment and functionality Compatible with rifles chambered for a designated cartridge specification Enables the case to be re-chambered in any SAAMI minimum size rifle chamber with minimal play Precision-engineered using monolithic reamers to attain exceptional concentricity and alignment accuracy
