This patented design has swiftly become the "state of the art" in straight-line bullet seaters, addressing the concentricity issues that have long affected other seating dies. The floating seating stem system enables tighter manufacturing tolerances, resulting in remarkable precision. The fit between the bullet guide and seating stem is so precise that the seating stem can be shown to "float" on a column of air, ensuring perfect alignment throughout the process. The seating stem is precision ground to match the bullet diameter exactly, enhancing the overall accuracy of the seating process. Additionally, alignment and consistency are improved by the close-fitting, precision-ground sleeve, which fully supports and aligns both the cartridge case and bullet before seating begins. The micrometer, calibrated in .001 inches increments, provides precise adjustments for seating depth and is infinitely adjustable. It also features a reset function, allowing you to return to your preferred seating depth with ease, ensuring consistency and repeatability with each reload.
