The Redding Competition Rifle Seating Die for 6mm Dasher is designed to provide the highest level of precision in bullet seating. This die addresses concentricity issues found in other seating dies, featuring a seating stem system that allows for tighter manufacturing tolerances. The bullet guide to seating stem fit is so precise that the seating stem can float on a column of air. The seating stem is precision ground to match bullet diameter exactly, making this die unparalleled in terms of precision.Alignment and accuracy are further enhanced by the complete support and alignment of the cartridge case and bullet in a close-fitting precision ground sleeve before seating begins. The micrometer allows for precise seating depth adjustments in .001 in. increments and is infinitely adjustable without clicks. Additionally, the micrometer features a setting option that enables you to set your preferred seating depth. Note: Not for use with compressed loads.
