Lee Precision Micrometer Full Length 3-Die Set Features The Lee Precision Micrometer Full Length 3-Die Set opens with a steel full length sizing die that resets .400 Legend brass to factory dimensions a critical step when working with mixed range cases of unknown firing history. A powder through expanding die follows flaring the case mouth just enough to seat a bullet without damaging the brass which helps extend case life across multiple reloading cycles. The micrometer bullet seating die lets a reloader dial in seating depth with repeatable precision a feature that matters for shooters chasing specific overall cartridge lengths for feeding or accuracy. Together these three dies cover every major step needed to turn resized brass into a finished .400 Legend round. This set is intended for reloaders working with mixed range brass since full length sizing handles the inconsistencies that come from cases fired in different rifles. A universal shell holder sized for .400 Legend is included removing the need to source one separately before starting to load. A powder measure and printed instructions with load data round out the kit giving new reloaders a safe starting point for working up loads. Finished in steel for durability this die set is built to handle the pressures of the .400 Legend cartridge over repeated use. For reloaders adopting .400 Legend this set offers a complete and precise solution to begin loading from a single boxed set.
