Area 419 Zero Modular Shellholder System Features The Area 419 Zero Modular Shellholder System solves a persistent reloading challenge by letting handloaders achieve full contact between the shellholder and die while still retaining the ability to dial in precise shoulder bump. Six precision ground stainless steel inserts allow adjustments in .002 inch increments giving reloaders a level of consistency that standard fixed shellholders cannot match. The kit includes three shellholder and extractor tops sized for common bolt face dimensions including .384 inch for .223 family cartridges .470 inch for .308 family cartridges and .540 inch for standard magnum cases. This traditional press version is built to work with standard reloading presses rather than the Zero press specific mounting system. An aluminum storage block keeps the base tops and all six headspace inserts organized and protected between reloading sessions preventing lost parts and keeping the precision ground surfaces free of damage. Because shoulder bump directly affects case life and chambering consistency this level of adjustability appeals to reloaders chasing maximum accuracy from their rifles. The system s modular design means reloaders can quickly swap tops to match whichever cartridge family they are working with that session. For serious handloaders who want repeatable fine tuned control over case sizing the Area 419 Zero Modular Shellholder System is a precision upgrade over standard fixed shellholders.
