Lee Precision builds the seater around a micrometer adjustment that dials seating depth in fine, repeatable increments, while the full-length sizer returns fired brass to factory dimensions for smooth chambering in any rifle. A universal shell holder, powder dipper, and load data round out the box, so the set favors hunters fireforming .280 brass and loading the Ackley for its full potential.
