The Bushing Bump Neck Sizing Die is a high-precision die designed to give you full control over the neck tension in your cases. This die enhances accuracy and extends case life by resizing the neck only as much as necessary, while still bumping the shoulder of the cartridge case to preserve overall concentricity. With improved concentricity, your ammunition will be more consistent and accurate. The die also decaps while sizing, streamlining the reloading process. It comes with three standard bushing sizes, carefully selected by Forster to suit a variety of reloading needs.
