Lee Micrometer Full-Length Die Set, 300 WSM

The Lee Micrometer Full-Length Die Set (Lee part no. 92401) is chambered for 300 WSM and pairs a Full-Length Sizing Die with a Micrometer Bullet Seating Die, the same two-die configuration Lee uses across its Micrometer die set line for other calibers. Full-length sizing brings the short, fat 300 WSM case back to SAAMI-spec dimensions, which matters for reliable feeding in short-action rifles built around this cartridge, while the micrometer seater lets you dial seating depth in thousandths of an inch instead of guessing by feel. For hunters chasing magnum performance out of a short-action rifle, this pairing covers the two most important steps of the process in one set.
