I use several X dies and I realy like them.
It works as avertised .

I also use LEE collet dies , it works on a different idea.
It just compresses the neck onto the depriming rod and leaves the rest of the case untouched .

Some times you will get case strech from the expander ball being pulled thru the neck , the LEE collet die stops this.

Both work , but in different ways.
