Area 419 Zero M-Series Sizing Die Features The Area 419 Zero M-Series Sizing Die was developed from years of testing as both a reloading equipment maker and a press manufacturer combining lessons learned from both sides of the process. A micrometer adjustable headspace and shoulder bump system allows precise repeatable shoulder control for consistent chambering. Precision ground expander mandrels come standard with a .002 inch neck tension mandrel with additional tension increments available through the Area 419 Mandrel Kit. A full length neck to extractor sizing spring ejects spent primers and replaceable steel decap pins keep the die running reliably over long reloading sessions. The reamer is cut to exacting dimensions to achieve a true size on fired brass helping eliminate the sticky bolt feel that can occur after a second firing with less precise dies. Hydraulic shoulder pressure relief further protects brass and improves consistency during sizing. Every die ships with an Area 419 ZERO Die Ring a spare decapping pin and the necessary install and removal tools giving reloaders everything needed to get started. Made entirely in the United States the Area 419 Zero M-Series Sizing Die is a serious upgrade for reloaders chasing match grade ammunition for sale at GrabAGun.
