Lyman Hartmetal Expander Button

The Lyman Hartmetal expander button significantly extends the service life of your sizing dies. Its specially developed, extra-hard and smooth Hartmetal material prevents case necks from stretching excessively during the sizing process, allowing you to maintain consistent case dimensions over extended reloading cycles. This translates to longer intervals between case trimming, reducing material costs and enhancing your reloading efficiency. The expander button is freely rotating on the decapping rod, ensuring precise centering within the case neck for consistent sizing results. For added versatility, the Hartmetal expander button can be positioned in two locations on the rod, allowing you to properly size even very short cases. The set includes an adapter compatible with all standard RCBS dies, so you can integrate this expander button into your existing reloading setup immediately.
