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, 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 die because it’s premier system of all the so-called ‘in-line’ seater systems that supports the entire outside diameter of the sized case rather than just the bullet and case neck.
We have continued to refine our seating stems to better fit newly designed ballistic tips and to match most very low drag (VLD) bullets. Our close fitting chamber (part#P-30) made with one-piece reamers ensures concentricity and accuracy.
Seater Dies are available in more than 70 calibers, either individually or bundled with a full length die in the bench rest die set.
