I have the instructions and can scan them if you like.

But it basically is like Unclenick said. By raising the ram with a cartridge in it, and screwing the die down until it contacts the case, you avoid overdoing it. It is very easy to see how far down the neck the sizer has resized.

Then you need to decide just how much of the neck you want to size, when you are done, tighten the lock ring.

Put your decapping/expander back in the die. Without a case in the press, raise the ram, and you can tell where to set it.

Hornady uses the elliptical expander in mine (don't know if your also have yours). To make it smoother, I chucked the expander rod in a drill press, and took some Flitz on a paper towel and polished it. It makes it come back through the neck more smoothly now.

I use mine on multiple calibers, so I just measure and record the position of the lock ring for each, and can return to the same setting without having to adjust in on again.
