The Forster Bushing Bump Neck Sizing Die is designed for precision reloaders who demand maximum control over neck tension and shoulder setback. This die allows you to size the case neck using interchangeable bushings while simultaneously “bumping” the shoulder for proper chamber fit.
By using caliber-specific bushings (sold separately), reloaders can fine-tune neck tension to match their brass thickness and accuracy requirements. The controlled shoulder bump ensures smooth chambering while maintaining optimal case life and alignment.
Precision-machined to Forster’s exacting standards, this die delivers excellent concentricity and consistent results, making it ideal for competitive shooters and long-range precision reloaders.
