The Bushing Full-Length Sizing Die provides advanced precision by offering precise control over the neck sizing tension in your reloaded brass, while also sizing the body and bumping the shoulder. This die improves accuracy and prolongs case life by sizing the shoulder and body just enough to fit into a minimum-sized SAAMI rifle chamber, while the bushing limits the amount of neck working. By minimizing neck overworking, this die preserves the integrity of the brass, ensuring longer case life and more consistent, reliable reloads.
