This patented design has quickly set the standard for straight-line bullet seaters, overcoming the concentricity issues found in other seating dies of this type. The floating seating stem system allows for tighter manufacturing tolerances, resulting in superior precision. The fit between the bullet guide and seating stem is so precise that the seating stem can be demonstrated to "float" on a column of air, ensuring perfect alignment during each operation. The seating stem is precision ground to exactly match the bullet diameter, enhancing the accuracy of the seating process. Alignment and consistency are further improved by the close-fitting, precision-ground sleeve, which fully supports and aligns the cartridge case and bullet before seating begins. The micrometer is calibrated in .001 inches increments, offering precise, infinitely adjustable seating depth. Additionally, the micrometer features a convenient reset function, enabling you to return to your preferred seating depth with ease, ensuring repeatable and consistent results with every reload.
