Forster 0.250" Bump Neck Sizing Die Bushing

An ultra-smooth bushing enhances the quality of loaded rounds. To achieve this, Forster employs a super-cooling cryogenic process. This cryogenic treatment of steel generates filler particles that refine and seal the surface of the steel. The bushings undergo heat treatment and are honed to the exact specified inside diameter. 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
