Redding’s Competition Seating Die represents the pinnacle of straight line bullet seating technology, addressing concentricity issues that plague conventional seating dies. The patented seating stem system incorporates manufacturing tolerances so tight that the bullet guide to seating stem fit allows the seating stem to float on a column of air, while the seating stem itself is precision ground to match bullet diameter exactly.
Both the cartridge case and bullet are fully supported and aligned within a close-fitting, precision ground sleeve prior to seating, which optimizes alignment and accuracy. The micrometer operates with .001″ increment calibration for exact seating depth control and features infinite adjustment without clicks. A setting feature on the micrometer lets you establish and return to your preferred seating depth. This die delivers the concentricity and consistency that precision handloaders and competitive shooters demand for the 300 Winchester Magnum.
