This patented design has quickly become the industry benchmark for straight-line bullet seaters, solving the concentricity issues that have long plagued other dies of this type. Thanks to the floating seating stem system, tighter manufacturing tolerances are now achievable, allowing for exceptional precision. The bullet guide and seating stem fit is so precise that the seating stem can 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, enhancing overall accuracy. Alignment is further improved by the close-fitting, precision-ground sleeve that fully supports and aligns the cartridge case and bullet before seating begins. The micrometer, calibrated in .001 inches increments, offers precise and infinitely adjustable seating depth. Additionally, the micrometer includes a convenient reset feature, allowing you to return to your preferred seating depth, ensuring consistent and repeatable results with every reload.
