The Redding Competition Seating Die has quickly established itself as the "state of the art" in straight line bullet seaters. This designed has beat the concentricity problems inherent in all other seating dies of this type. Tighter manufacturing tolerances have been made possible due to the details of the patented seating stem system. The bullet guide to seating stem fit is so precise that the seating stem can actually be demonstrated to "float" on a column of air.
The seating stem is precision ground to exactly match bullet diameter. No seating die on the market is built to this level of precision. Alignment and accuracy are enhanced by the cartridge case and bullet being completely supported and aligned in a close fitting, precision ground sleeve before the bullet seating begins. The micrometer is calibrated in .001" increments for precise seating depth and is infinitely adjustable (without clicks). The micrometer also has a "zero" set feature that allows you to zero the micrometer to your rifle or favorite seating depth.
