The Bushing Full-Length Sizing Die provides advanced precision by giving you precise control over the neck sizing tension in your reloaded brass, while also sizing the body and bumping the shoulder. This die enhances 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 neck working. By minimizing overworking the neck, this die preserves the integrity of the brass, ensuring longer case life and more consistent, reliable reloads.
