Anyone try the RCBS X-Die?

Hi

Description of the RCBS X-Die:

"The patented X-Die eliminates the need for repeated trimming after an initial case trim of .020" off the maximum case length. A specially designed mandrel contacts the case mouth and reduces the growth rate. Because of an extremely close tolerance between the mandrel and die neck wall, the neck wall of the case does not thicken as the case length is pushed back. Cases repeatedly sized in the X-Die will initially grow a few thousandths of an inch, then stabilize below the maximum case length with no discernable loss of accuracy or case life. Set contains X-Die Full Length Sizer Die and Seater Die. Shellholder sold separately. "

Has anyone tried this die?

Thanks

Yes, in .223 and .30/06. They work as advertised.

Do you find that your cases wind up being all the same length after they're shot and have lengthened?

I've just found that I don't have to trim them. I use a "pass/fail" method to check my case length, so I don't really notice shorter cases.
What remains to be seen is where the brass IS going when it flows, if it's not going into the neck. So far, they've made very accurate loads.

Are you using the x-die seater die too?

I called RCBS and they said the brass flows into the neck like usual.
But since the instructions say to, basically, cut the brass short(er) at the start...The brass grows into the length.
So cut first then grow.
Rather than the usual grow then cut.
