This patented design has quickly become the gold standard in straight-line bullet seaters, solving the concentricity issues that have long plagued other seating dies. The innovative floating seating stem system enables tighter manufacturing tolerances, delivering superior 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, ensuring perfect alignment during every use. The seating stem is precision ground to match the bullet diameter with exacting accuracy. The alignment and accuracy are further enhanced by the close-fitting, precision-ground sleeve, which fully supports and aligns both 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 reset feature that allows you to return to your preferred seating depth, ensuring consistency and repeatability with each reloading session.
