hydraulic form dies anyone use them?

I saw this, and was wondering if anyone used them for their wildcats, or AI cases to cut down on fireforming.
It seems like it would be of more benefit when drasticially changing case taper and case/shoulder junction from the parent case.

Just trying to learn a little about caseforming 101 and introduction to wildcatting.
Rumbler's not here so I can't PM him like I used to to bat ideas/concepts off of him.

I never have used any thing like that to form cases but have used hydraulic pressure to remove berdan primers from cases. It worked well enough but was messy.
