This patented design quickly became the industry leader in straight-line bullet seaters, effectively overcoming the concentricity issues that have long plagued other seating dies. The innovative floating seating stem system allows for tighter manufacturing tolerances, ensuring exceptional precision. The fit between the bullet guide and seating stem is so precise that the seating stem can actually be demonstrated to "float" on a column of air, ensuring flawless alignment. The seating stem is precision ground to exactly match the bullet diameter, resulting in superior accuracy. Alignment and consistency are further enhanced by the fully supported and aligned cartridge case and bullet, housed in a close-fitting, precision-ground sleeve before the seating process begins. The micrometer is calibrated in .001 inches increments, offering precise and infinitely adjustable seating depth. Additionally, the micrometer includes a feature that allows you to reset it to your preferred seating depth, ensuring repeatable, consistent results with every reload.
