Forster pioneered the first die of its kind in the market and it remains the leading straight-line seater die available. The sliding die chamber features a concentric bullet channel that is marginally larger than the bullet diameter, ensuring a precise fit for straight-line (co-axial) seating. The hand-polished bullet seating stem guarantees consistent reloading performance. The seater die is compatible with most standard reloading presses and its non-crimping design delivers accuracy, consistency and perfect alignment. Forster/Bonanza secured U.S. Patent #3,440,923 for the original Bench Rest Seater Die design, which incorporates a specially machined, close-fitting chamber that maintains perfect alignment of the case, bullet and seating stem. This innovative chamber design remains a defining feature of our Bench Rest seater dies, as it represents the premier system among all in-line seater systems, supporting the entire outside diameter of the sized case rather than just the bullet and case neck. We have continually refined our seating stems to accommodate newly designed ballistic tips and to align with most very low drag (VLD) bullets. Our close-fitting chamber (part #P-30), crafted with one-piece reamers, ensures concentricity and accuracy. Our precision-engineered, caliber-specific sliding die chamber ensures optimal alignment of the bullet, case and seating stem during the seating process, enhancing accuracy and consistency The non-crimping design ensures precision, uniformity and near-perfect alignment, optimizing performance and reliability in technical applications
