At this time, dies are ONLY shipping with ZERO M-Series Shellholders. If you are using ANY other press, you will need to wait on the future release of a traditional, or non-ZERO shellholder.

If you have one of our existing headspace-adjustable shellholder kits, it WILL NOT work with the M-Series die, as this die requires a large-diameter shellholder.

This is a 1-1/4″ die, and requires a Hybrid or 1-1/4″ Turret on your ZERO (or other press). It CANNOT be used with a 7/8″ Turret or other 7/8″ press.

The ZERO M-Series Sizing die is the culmination of years of testing, research, trial, error, frustration, and finally, discoveries.

As Reloaders, we knew we needed a die to do certain things, but as the makers of the ZERO Reloading Press, we also learned a huge amount about what other dies did well or did poorly, and what our customers were struggling with on a daily basis.

With the ZERO M-Series Sizing Die, we think we have produced a sizing die that is capable of producing the finest, match-grade ammunition, as well as being user-friendly to new and learning reloaders.

Sizing brass doesn’t have to be complicated. It doesn’t have to require years of trial and error. It just needs equipment, made with the end-user in mind, designed with the understanding that a die is part of an ecosystem of parts. A press, a die, the brass, the rifle – they all have to work together and be designed with one another in mind. This is that. Introducing, the ZERO M-Series Sizing Die.

KEY FEATURES

• Micrometer Adjustable Headspace/Shoulder Bump

After testing them all, and finding everything we like and didn’t like, and working with thousands of customers and a variety of industry partners, we believe this is what a sizing die should be. We think you’ll agree.

IMPORTANT NOTE – THESE DIES ARE NOT COMPATIBLE WITH STANDARD SHELLHOLDERS, AND REQUIRE A LARGER DIAMETER SHELLHOLDER RIM. IF YOU DO NOT HAVE A ZERO M-SERIES SHELLHOLDER, YOU CANNOT USE THIS DIE.
