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.
