The Lee Precision Ultimate Rifle 4-Die Set for .22-250 Remington is a comprehensive kit designed to give reloaders maximum versatility. Its key feature is the inclusion of two different sizing dies: a full-length sizing die for creating reliable ammunition that will function in any rifle, and a collet neck sizing die for producing highly accurate, custom-fit rounds for a specific bolt-action rifle. The set is completed by a dead length bullet seating die for precise alignment and a factory crimp die for consistent performance. This all-inclusive package also contains a shell holder and a powder dipper, providing everything needed to load for either perfect reliability or top-tier accuracy.
