Lee Precision 9x21 3-Die Set Features The Lee Precision 9x21 3-Die Set is built around a steel full length sizing die which resizes fired cases back to factory specifications for reliable chambering across different 9x21 pistols. Because this is a steel die reloaders will want to apply resizing lubricant to each case before sizing which is standard practice for steel die sets and helps prevent cases from sticking in the die during the sizing stroke. The powder through expanding die flares the case mouth to accept a new bullet without damaging the case or the bullet during seating. The bullet seating die then seats the new bullet to the correct depth for a properly sized finished cartridge. A universal shell holder is included in the set removing the need to source one separately for 9x21 reloading along with instructions to help guide reloaders through the process. This complete 3-die approach covers the essential stages for producing 9x21 ammunition on a standard single-stage or turret reloading press. The 9x21 cartridge while less common than mainstream 9mm offerings has a dedicated following among reloaders who rely on dies like this set to keep their supply going. For shooters reloading 9x21 ammunition this Lee Precision die set provides an affordable complete solution.
