The Bushing Full-Length Sizing Die provides advanced precision, allowing you to finely control the neck sizing tension in your reloaded brass while also resizing the body and bumping the shoulder. This die improves accuracy and extends case life by sizing the shoulder and body just enough to fit into a minimum-sized SAAMI rifle chamber, while the bushing limits excessive neck working. This ensures consistent performance and reduces wear on your brass. The kit includes three bushings, giving you the flexibility to adjust the die for optimal reloading results tailored to your needs.
