The Redding Competition Seating Die is a straight-line bullet seater engineered for precision reloading of the 6 mm Dasher cartridge. It uses a precision-ground seating stem and a close-fitting sleeve to support and align the cartridge case and projectile during seating. The micrometer is calibrated in .001 inch increments and is infinitely adjustable to allow precise and repeatable seating depths.
