This patented design has rapidly become the "state of the art" in straight-line bullet seaters, solving the concentricity issues that have long plagued other seating dies of this type. 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 be demonstrated to "float" on a column of air, guaranteeing perfect alignment with each use. The seating stem is precision ground to match the bullet diameter exactly, contributing to unparalleled accuracy. Alignment and consistency are further optimized by the close-fitting, precision-ground sleeve that fully supports and aligns both the cartridge case and bullet before seating begins. The micrometer is calibrated in .001 inches increments, offering precise, infinitely adjustable seating depth. Additionally, the micrometer includes a reset feature, allowing you to easily return to your preferred seating depth, ensuring repeatable and consistent results every time you reload.
