Shooting Dillon 650 Tool Head, Zero Play, Free Float Ready Blue

What does the floating die tool-head do? This tool-head has lock rings that allow the sizer and seater dies to float. This floating action allows the dies to center themselves exactly over each cartridge for the best possible alignment and more concentric. What is Zero Play? This tool-head does not use original toolhead pins supplied by dillon. This toolhed is bolted with two M3 bolts and lifts toolhead into upmost position. When you cycle cases downwards toolhead does not move and cases go out in straight line. Best practice is to loosen M3 bolts a little bit and push index shell-plate with case in to dies and tighten M3 bolts in toolhead best position. What is concentricity? Concentricity refers to how straight the b. is on top of the loaded round. A b. that is straight will enter the rifling that way. B. that enter the rifling slightly crooked, do not go straight with their highest accuracy. What's wrong with using the OEM toolheads? The Dillon presses are great machines made to high quality standards. However, the cast toolheads have limitations. How do we know if the toolhead flange is flat? How do we know that each threaded station in the toolhead is in perfect alignment with the shell-plate? How do we know that the stations are equally spaced? All of these areas compound for possible misalignment's and lead to a. that isn't quite as concentric as it could be. The toolhead is the final link between your dies and your press so it only makes sense that quality is extremely important. With over 100,00 USD of dies, powder measure, and other accessories mounted in your toolhead, don't you want to know it's the best available. These toolheads are made to the highest standards. The are CNC machined from 6082 aluminum, which is much stronger and has less flex than a cast toolhead. Critical dimensions are machined in a single operation, ensuring that all surfaces are true and aligned relative to each-other.
