Do Not Cam Over!

So I am reading the instructions that came with my new RCBS cowboy action dies for .38/.357....and I come across the section about setting up your sizer die and it says in BOLD letters....DO NOT CAM OVER.

Now I am assuming that this means that when the ram is fully extended up, that you should screw the die down to touch it. You then tighten down so that there is not that "over the hump finish" to the stroke when you push the case up into the die?

Guessing here, hope that description was useful in understangin my question.

I don't remember reading that warning in other instructions included with my other dies.

What am I missing?

Camming over is when the press ram reaches its highest point and the handle continues to move a small amount. It amounts to going over center.

At the center point you are applying a tremendous amount of force between the shellholder and the die due to the extreme leverage of your press.

The reason for the advice is to prevent damaging the dies by applying an excessive amount of force.

You should not cam-over carbide dies because you'll crack the carbide insert. It is brittle.
