This patented design has rapidly become the "state of the art" in straight-line bullet seaters, overcoming the concentricity issues that have long troubled other seating dies. The innovative floating seating stem system enables tighter manufacturing tolerances, enhancing overall precision. The fit between the bullet guide and seating stem is so exact that the seating stem can be shown to "float" on a column of air, ensuring flawless alignment with every use. The seating stem is precision ground to exactly match the bullet diameter, ensuring superior accuracy. Alignment and consistency are further improved by the close-fitting, precision-ground sleeve, which fully supports and aligns both the cartridge case and bullet before the seating process begins. The micrometer is calibrated in .001 inches increments, allowing for precise, infinitely adjustable seating depth. Additionally, the micrometer includes a reset function, enabling you to return to your preferred seating depth easily, ensuring repeatable, consistent results with each reload.
