The secret to perfect alignment is holding the bullet, case, and seating stem in the same close-fitting chamber for the entire seating operation.
Forster Products offers two styles of Bench Rest Seater Dies:
Years ago, Forster/Bonanza obtained U.S. Patent #3,440,923 for the design of the original Bench Rest® Seater Die. That patent covered the use of a specially machined 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 “in-line,” or co-axial, seater systems, which support the entire outside diameter of the sized case.
