Roll Sizing Data?

[Woodsy]

Has anyone analyzed the effect of roll sizing brass?
If they/you have re-sized similar bulged brass casings with a sizing die on one piece and then another piece with a roll sizer to compare the difference?
Have you seen pictures of cases split into two after being sized by these two methods to observe the effects on case wall thickness?
Just looking for some hard data.

The machine is cute, but damn expensive. So, NOT I. I bet one or two might have, but good luck getting them to post...

I heard Chuck Norris rolls them between his thumb and forefinger and that is all the sizing they need...
