RCBS "X Dies"

[FinsnFur]

Anyone ever use, see, or try these?
Sounds interesting but almost unbelievable. Miracle dies?

The RCBS site dont say a whole lot about them that I can find, other then price.
But here's a link that describes them.

Looks like a collet die of some sort

I have a couple sets of them that I think were given to me as gifts from my brother inlaw (.222 and 7mm-08).  I tried them, and found no difference (atleast from what I could see) between them and regular dies.
Oh Jimbo, you are becoming "hooked" on reloading and don't even know it.   You'll be rolling in the money you'll save by reloading.  Trust us..

Shut up Dave, your making me nervous

I asked a guy at work today who has used them and he claims they act like carbide dies.
