Forster created the first die of its kind on the market, and it’s still the best straight-line Seater Die anywhere. The sliding Die Chamber has a concentric bullet channel just slightly larger than the bullet diameter. This tight fit ensures straight-line (co-axial) seating.

The hand-polished Bullet Seating Stem provides consistent reloads. The Seater Die adapts to most standard reloading presses. Its 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 “in-line” seater systems, which support 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 80 calibers, either individually or bundled with a Full Length Sizing Die in the Bench Rest Die Set.
