Product Description The AREA 419 Zero Modular Shellholder System is a precision-engineered reloading accessory designed to bring unmatched consistency and repeatability to your sizing process. Through extensive testing with the ZERO press and other traditional presses, Area 419 discovered that direct contact between the shellholder and the die produces the most consistent sizing results. The Zero Modular Shellholder System makes that possible while still giving you full control over your shoulder bump adjustment. Using a set of six precision ground stainless steel headspace inserts that step in .002" increments, you can fine-tune your setup to match your exact die without sacrificing contact or consistency. Whether you&';re running a ZERO press or a conventional press, this system offers a flexible, highly repeatable solution for serious reloaders.
