Forster 0.313" Bump Neck Sizing Die Bushing

The cryogenic process is integral to achieving the desired properties in the bushings. It involves cooling the steel to extremely low temperatures, which alters its microstructure. This transformation results in a more durable and resilient material, capable of withstanding high levels of stress and wear. The outcome is a bushing that not only performs better but also lasts longer. Forster neck size bushing bump inserts are specifically engineered for exclusive use with the Forster precision plus bushing bump die The bumpers are precision-engineered with 0.001 inches tolerances and undergo cryogenic treatment to enhance surface smoothness and durability
