Forster introduced the first straight-line Seater Die and it remains the best on the market. Featuring a sliding Die Chamber with a concentric bullet channel just slightly larger than the bullet diameter, this tight fit ensures precise, straight-line (co-axial) seating. The hand-polished Bullet Seating Stem provides reliable and consistent reloads, while the Seater Die is designed to work with most standard reloading presses. Its non-crimping style guarantees unmatched accuracy, consistency and perfect alignment. Years ago, Forster/Bonanza earned U.S. Patent #3440,923 for the innovative design of the original Bench Rest Seater Die. This patent covered the specially machined, close-fitting chamber that perfectly aligns the case, bullet and seating stem. The design remains the hallmark of Forster's Bench Rest Seater Dies, as it is the premier "in-line" seater system that supports the entire outside diameter of the sized case, rather than just the bullet and case neck. Forster has continued to refine the seating stems to ensure compatibility with the latest ballistic tips and very low drag (VLD) bullets. The close-fitting chamber (part #P-30), made with 1-piece reamers, ensures exceptional 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, offering shooters unmatched performance for precision reloading.
