Area 419 Zero Sizing Die Mandrel Kit Features The Area 419 Zero Sizing Die Mandrel Kit is a core part of the modular design behind the company s ZERO sizing dies which rely on a precision ground full length mandrel to control neck tension. Each kit includes four interchangeable mandrels ground from 17-4PH stainless steel and black nitrided for smooth consistent operation over thousands of cycles. When combined with the mandrel that ships with a ZERO M-Series or S-Series die the kit gives reloaders neck tension adjustments in .0005 inch increments ranging from .0005 to .0025. This fine level of control lets precision shooters tune bullet grip to the exact feel their rifle responds to best. Because the mandrels are fully interchangeable reloaders can swap tension levels quickly at the bench without needing a separate die for every neck tension they want to test. A spare decapping pin is included in every kit giving reloaders a ready replacement in case the installed pin wears or breaks during a reloading session. Compact at just 4 by 4 by 1 inches and weighing half a pound the kit stores easily in a reloading bench drawer or range bag. For precision reloaders working with 6mm cartridges who want granular control over neck tension the Area 419 mandrel kit is available for sale at GrabAGun.
