||Bench Rest® Seater Dies. Non-crimping style provides accuracy, consistency and perfect alignment. 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 Dies, because it's the 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 VLD (Very Low Drag) bullets. Our close fitting chamber (part #P-30) made with one-piece reamers ensures concentricity and accuracy.
Now Available: Customized Neck Sizing Service For Bench Rest® Sizing Dies
For new or used Forster Bench Rest® sizers
If you're worried about overworking the necks of your case or if you want to size your cases without the expanding ball in place, Forster now offers an optional machining service that's just right for you. For a low cost custom honing fee, we will open the neck area of your full length or neck sizing die to your specified dimension. Remember to allow for about .002" of springback as the brass is withdrawn from the die.
Compare our Bench Rest® Seater Die design to the exaggerated sectional drawing of a conventional bullet seater die as shown here:
Exaggerated Sectional of a Conventional Bullet Seater
In a conventional seating die containing a fixed chamber and a fixed seating stem, it's possible to start the bullet into the neck at an angle. Due to the design, the case is outside the die at an amount equal to the depth of the bullet entering the case. At the moment of entry, the case is not contained in or guided by the chamber. In the Forster Bench Rest® Seater Die, both the case and the bullet are held in a close fitting chamber while the bullet is being seated.
