The Redding seating die features a bullet guide, an integrated crimp ring and an appropriate seating plug. Each die is constructed from the highest quality alloy steels available and is machined on Hardinge super-precision lathes, which are capable of maintaining the industry's most stringent tolerances. The dies undergo heat treatment in atmospherically controlled furnaces and are hand-polished to ensure smooth and flawless operation. Designed to maintain tolerances and ensure longevity, these dies are thoroughly inspected and ultrasonically cleaned prior to packaging.
