Area 419 Zero M-Series Sizing Die Features The Area 419 Zero M-Series Sizing Die resizes 6mm Creedmoor brass with a micrometer adjustable headspace and shoulder bump system letting the reloader dial in exact shoulder setback for consistent chambering and extended brass life. A precision ground expander mandrel ships with every die and each one includes a 0.002 inch neck tension mandrel as standard with additional tension increments available through the Area 419 Mandrel Kit. Full-length neck to extractor sizing is cut to exacting reamer dimensions for a true size that eliminates the sticky bolt feel often experienced after a case has been fired a second time. A spring ejection system clears spent primers automatically and replaceable steel decap pins keep the die running without costly part replacements. Because this is a 1-1/4 inch die it requires a Hybrid or 1-1/4 inch turret on a Zero press or other compatible press and it cannot be used in a standard 7/8 inch turret or press. It is also not compatible with standard shellholders requiring the larger diameter rim of a Zero M-Series shellholder which ships together with this die. Hydraulic shoulder pressure relief protects the press and die from the sudden pressure spikes that can occur during sizing extending the service life of the whole system. Made entirely in America and backed by Area 419 s reloading expertise the Zero M-Series Sizing Die gives 6 Creedmoor reloaders a path to match-grade ammunition without years of trial and error.
