This patented design has quickly set the standard for straight-line bullet seaters, effectively overcoming the concentricity issues that other seating dies of this type face. The innovation of the floating seating stem system allows for tighter manufacturing tolerances, ensuring unmatched precision. The fit between the bullet guide and seating stem is so exact that the seating stem can be demonstrated to "float" on a column of air, providing perfect alignment throughout the process. The seating stem is precision ground to precisely match the bullet diameter, enhancing accuracy. The cartridge case and bullet are fully supported and aligned within a close-fitting, precision-ground sleeve before the seating process begins, further improving alignment and consistency. The micrometer is calibrated in .001 inches increments, providing precise and infinitely adjustable seating depth. Additionally, the micrometer includes a reset function, allowing you to easily return to your favorite seating depth, ensuring repeatable, consistent results with each reloading session.
