Area 419 Zero M-Series Sizing Die Features The Area 419 Zero M-Series Sizing Die features a micrometer adjustable headspace and shoulder bump system that lets a reloader precisely control how much the case shoulder is set back during sizing which is critical for both chamber fit and brass life. Precision ground expander mandrels reamed to exacting dimensions deliver a true size that eliminates the sticky bolt feel some reloaders experience after a case has been fired and resized a second time. Every die ships with a .002 neck tension mandrel installed and additional tension increments are available separately through Area 419 s mandrel kit for reloaders who want to fine-tune neck tension further. A hydraulic shoulder pressure relief system reduces the stress placed on the case shoulder during sizing helping extend brass life across multiple reloading cycles. Full-length sizing from the neck down to the extractor groove ensures cases chamber reliably and consistently an important detail for reloaders chasing repeatable accuracy. A spring ejection system for spent primers along with replaceable steel decapping pins keeps the die running cleanly through high-volume reloading sessions. Every die ships complete with an Area 419 Zero Die Ring a spare decapping pin and the install and removal tools needed to use it so reloaders have everything required out of the box. Note that this is a 1-1/4 inch die requiring a hybrid or 1-1/4 inch turret and it will not fit a standard 7/8 inch press or turret.
