The Bushing Bump Neck Sizing Die is a precision-engineered tool that gives you complete control over the neck tension of your cases. By sizing the neck just enough while still bumping the shoulder of the cartridge case, this die helps maintain optimal concentricity, which enhances accuracy and prolongs case life. The result is more consistent, accurate ammunition. Decapping is seamlessly integrated into the sizing process, making reloading more efficient. The die comes with three standard bushing sizes, carefully selected by Forster to ensure the best fit for your reloading needs.
