This patented design has quickly become the gold standard in straight-line bullet seaters, resolving the concentricity issues that plague traditional seating dies. Thanks to the innovative floating seating stem system, tighter manufacturing tolerances are now possible, ensuring superior precision. The fit between the bullet guide and seating stem is so exact that the seating stem is demonstrated to "float" on a column of air, ensuring optimal alignment. The stem is precision ground to match the bullet diameter with exacting accuracy. By fully supporting and aligning both the cartridge case and bullet in a close-fitting, precision-ground sleeve, the system guarantees enhanced alignment and accuracy before seating begins. The micrometer is calibrated to .001 inches increments for incredibly precise seating depth adjustments and offers infinite adjustability. Additionally, the micrometer features a convenient re-set function, allowing you to easily return to your preferred seating depth, further enhancing the consistency and ease of use.
