The Redding Neck Expander Die combines affordability, exceptional steel quality and the assurance of a lifetime guarantee, making it a reliable choice for reloaders focused on precision and brass longevity. Specifically designed for rifle cartridges, this die gently bells the mouth of the case, reducing stress on the brass to extend its lifespan while improving accuracy and performance. By sizing only the neck and not the body or shoulder, it ensures precise alignment, but it's important to note that fired cases should not be interchanged between rifles of the same caliber. Built with Redding's commitment to quality, this die offers both durability and precision for dedicated reloaders.
