Lee Precision Micrometer 2-Die Set Features The Lee Precision Micrometer 2-Die Set is built around a full length sizing die which resizes brass cases of mixed origin back to proper dimensions for reliable chambering. This makes the set especially useful for reloaders working with once fired range brass from various sources since full length sizing restores consistent case dimensions regardless of where the brass originated. Paired with the sizing die is Lee s micrometer bullet seating die which allows seating depth to be dialed in and repeated precisely from one loading session to the next. This combination helps reloaders produce consistent ammunition without needing to guess at seating adjustments each time they load a batch. The set ships with a universal shell holder sized for 8x57 Mauser brass removing the need to source a separate shell holder before getting started. A powder dipper is also included giving reloaders a simple tool for measuring propellant charges by volume. Instructions with load data round out the package providing a reference point for safe starting loads in this chambering. For 8x57 Mauser shooters setting up a reloading bench this Lee Precision die set offers a complete ready to use solution for producing accurate ammunition.
