A single stroke seats the gas check, swages the bullet to the proper diameter, and lubricates it. SAECO's Lubri-Sizer features a pressurized reservoir that lubricates from 20 to 50 bullets between turns of the lube control handle. Two precision parallel guid rods assure proper alignment of the top punch and sizing die, resulting in maximum bullet concentricity. Those who prefer to shoot bullets "as cast" will appreciate SAECO's exclusive swing out gas check seater which allows the option of seating gas checks without sizing. A combination of compound leverage and extra length operating handle substantially reduces physical effort. Sizing Dies and Top Punches are not uncluded and should be ordered seperately according to caliber and bullet design.
