Lee Precision Micrometer Features The Lee Precision Micrometer full length sizing die resizes spent .338 Win Mag brass back to factory dimensions making it the right choice for reloaders working with new or mixed range cases rather than fire-formed brass from a single rifle. A floating bullet guide centers both the case mouth and the projectile during seating which reduces bullet runout and helps keep each loaded round concentric. Dead-length seating has the die contact the shell holder directly ensuring a uniform seating depth on every stroke of the press regardless of minor variations in case length. That combination of full length sizing and dead-length seating gives a reloader consistent cartridge dimensions from the first round to the last. The micrometer bullet seating die adds a laser-engraved adjustment dial that lets a handloader dial in and return to a precise seating depth without guesswork or trial and error. The seater sleeve can also be reversed to seat and crimp in a single operation simplifying the loading process for cartridges that benefit from a roll crimp. Included in the set are a universal shell holder a powder measure scoop and load data giving a reloader the accessories needed to start loading right out of the box. Built for mixed and range brass the Lee Precision Micrometer 2-Die Set is a practical complete solution for .338 Win Mag handloaders.
