This patented design has rapidly become the gold standard in straight-line bullet seaters, resolving the concentricity issues that have long plagued traditional seating dies. The floating seating stem system enables tighter manufacturing tolerances, which translates into superior 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, ensuring flawless alignment with every operation. The seating stem is precision ground to match the bullet diameter exactly, enhancing accuracy. Alignment and consistency are further optimized by the close-fitting, precision-ground sleeve that completely supports and aligns the cartridge case and bullet before seating begins. The micrometer, calibrated in .001 inches increments, allows for precise adjustments to seating depth and offers infinite adjustability. Additionally, the micrometer includes a reset feature, allowing you to return to your preferred seating depth effortlessly, ensuring repeatable and consistent results with every reload.
