TO ORDER ONE FOR YOUR ZERO OR TRADITIONAL RAM-STYLE PRESS, CLICK HEREThe 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 doesnt have to be complicated. It doesnt 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.
