For reloaders who choose to retain the fire formed dimensions of their cases rather than resizing the entire case, neck sizing-only dies fit a definite need. Although they only work the necks of cases, they do eliminate some problems associated with excessive headspace. Neck sizing can also prolong case life. Our Bench Rest® Seater Die features a specially machined, close fitting chamber that holds the case, the bullet and the seating stem all in perfect alignment. This innovative chamber design is still the hallmark of our Bench Rest® Seater Dies, because it's the premier system of all the so-called "in-line" seater systems that actually supports the entire outside diameter of the sized case rather than just the bullet and case neck. Set includes Neck Sizer Die and Bench Rest Seater Die. Shellholder sold separately.
