The Lee Micrometer Full Length Die Set in 300 H&H Magnum (brand part no. 92410) supports one of the great classic belted magnums, a cartridge whose factory ammunition grows scarcer every year while its rifles keep hunting. Lee Precision pairs a full-length sizing die that restores fired belted cases to factory dimensions with a micrometer bullet seating die for exact, repeatable depth settings, and includes the universal shell holder, powder scoop, and load data to run the set from day one. Standard 7/8-14 threads fit any common press. Among reloading dies, this set favors 300 H&H owners keeping pre-64 Winchesters and custom magnums in the field.
