Forster neck bushings allow case necks to be sized to exact requirements in a Bushing Bump Neck Sizing Die. The .311 diameter bushing is designed for precise cartridge reloading applications. Forster offers flexibility, with bushing sizes available in .001″ increments, allowing reloaders to customize neck sizing based on their brass specifications and chamber requirements.
Forster neck bushings are machined to a superior interior finish for “smooth as silk” neck sizing. An ultra smooth bushing produces better loaded rounds, so Forster uses a super-cooling cryogenic process to achieve exceptional surface quality. This item is one bushing only; the die is not included, making it an ideal replacement or spare bushing for existing Bushing Bump Neck Sizing Dies.
The .311 diameter bushing enables fine control over neck tension during the reloading process, which is essential for achieving consistent cartridge quality and improving shot-to-shot accuracy. Whether you’re working with tight-chambered rifles or managing varying brass neck wall thickness, this precision-engineered bushing from Forster Products delivers the reliability and consistency that serious reloaders demand.
