Forster revolutionized the reloading world with the introduction of the first straight-line Seater Die and it remains the best on the market today. Featuring a sliding Die Chamber with a concentric bullet channel just slightly larger than the bullet diameter, the design ensures precise, straight-line (co-axial) seating. This tight fit guarantees alignment and accuracy with every round. The hand-polished Bullet Seating Stem further enhances consistency for reloads, while the Seater Die adapts to most standard reloading presses. Its non-crimping style supports flawless accuracy, consistency and 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 unique chamber, which holds the case, bullet and seating stem in perfect alignment, a hallmark that remains integral to Forster's Bench Rest Seater Dies. The system's "in-line" design supports the entire outside diameter of the sized case, rather than focusing solely on the bullet and neck, making it the premier system for precise reloading. Forster continues to refine its seating stems, ensuring compatibility with modern ballistic tips and very low drag (VLD) bullets. The close-fitting chamber (part #P-30), made with 1-piece reamers, ensures unmatched concentricity and accuracy. Seater Dies are available in 80 calibers, either individually or as part of the Bench Rest Die Set, which includes a Full-Length Sizing Die.
