This patented design quickly became the benchmark for straight-line bullet seaters, solving the concentricity issues that have long troubled other seating dies. The floating seating stem system allows for tighter manufacturing tolerances, ensuring exceptional precision. The fit between the bullet guide and seating stem is so exact that the seating stem can actually be demonstrated to "float" on a column of air, ensuring perfect alignment every time. The seating stem is precision ground to exactly match the bullet diameter, contributing to flawless accuracy. Alignment and consistency are further enhanced by the fully supported and aligned cartridge case and bullet, which are housed in a close-fitting, precision-ground sleeve before the seating process begins. The micrometer is calibrated in .001 inches increments for precise adjustments to seating depth, offering infinite adjustability. Additionally, the micrometer features a convenient reset function, allowing you to return to your preferred seating depth with ease, ensuring repeatable and consistent results with each reloading session.
