This patented design quickly became the industry leader in straight-line bullet seaters, solving the concentricity issues that have historically plagued other seating dies. The floating seating stem system enables tighter manufacturing tolerances, ensuring exceptional precision. The bullet guide to seating stem fit is so precise that the seating stem can be demonstrated to "float" on a column of air, guaranteeing perfect alignment throughout the seating process. The seating stem is precision ground to exactly match the bullet diameter, ensuring flawless accuracy. Alignment and consistency are further enhanced by the close-fitting, precision-ground sleeve that fully supports and aligns both the cartridge case and bullet before the seating operation begins. The micrometer is calibrated in .001 inches increments, offering precise, infinitely adjustable seating depth. Additionally, the micrometer features a reset function, allowing you to return to your preferred seating depth, ensuring consistency and repeatability with each reloading session.
