Redding 1" Full Length Series Z Die Redding Reloading Equipment Proudly Announces The New Benchmark in Precision Handloading Dies Redding Reloading Equipment announces the new benchmark in precision handloading. The revolutionary "Z Series" Die Family utilizes Larger, Stronger and more Robust 1" die bodies. Redding engineering has proven that the modern high performance cartridge designs of today are severely taxing the capabilities of traditional 7/8" reloading dies. The 7/8" diameter became the industry standard in the post WWII era, but today's new cartridge designs provide numerous reasons to question that standard. In short, it is all about the strength of material, the stresses induced and the deformation that occurs in the die itself. With the revolutionary "Z Series" Dies, the handloader can see, feel and measureand the difference. Based on relative strength, the "Z Series" Dies are as much as 2X stronger than traditional 7/8" dies. Extensive lab testing has shown that this increased strength and rigidity provides significantly reduced sizing effort as well as more consistent and measurable sized case dimensions. The initial "Z Series" offering will include single dies, die sets and bushing die sets in (31) popular cartridges from 284 Win to 375 (9.5x77). The new "Z Series" Dies are also readily adaptable to most reloading presses marketed today with a simple die bushing change. Redding is now offering new "Z Series" Turret heads to increase the flexibility of the ever-popular Redding T-7 Press.
