Full-length die sets for bottleneck cases consist of two key dies. The Full-Length (FL) resizing die includes a decapping rod assembly and a neck expander (size button), allowing for precise resizing of the case. The seating die (ST) comes equipped with a bullet guide, a built-in crimp ring and the appropriate seating plug, ensuring that the bullet is seated properly and securely crimped. These die sets are ideal for reloaders looking to produce consistent, accurate ammunition with reliable resizing and bullet seating.
