The Bushing Bump Neck Sizing Die is a precision-engineered tool that provides control over the neck tension in your cases, ensuring optimal performance. By sizing the neck only as much as necessary while still bumping the shoulder of the cartridge case, this die maintains overall case concentricity, which improves both accuracy and extends case life. With improved concentricity, you will produce more consistent and accurate ammunition. The die also decaps while sizing, streamlining the reloading process. It comes with three standard bushing sizes, specially selected by Forster, to give you the flexibility for precise reloading.
