The Bushing Bump Neck Sizing Die is a high-precision tool that allows you to fine-tune the amount of neck tension in your cases for optimal performance. By sizing the neck just enough while still bumping the shoulder of the cartridge case, it ensures that case concentricity is maintained, improving both accuracy and extending case life. This enhanced concentricity results in more consistent and accurate ammunition. The die also performs decapping during the sizing process, streamlining your reloading steps. It comes with three standard bushing sizes, carefully selected by Forster, to provide the best fit for your needs.
