The Bushing Full-Length Sizing Die provides advanced precision by allowing you to precisely control the amount of 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 the working of the neck. By reducing unnecessary neck tension, this die ensures the brass maintains its integrity, leading to more consistent reloads and a longer lifespan for your cases.
