I recieved my 243 ackley hydro dies. A after messing with them for a couple of days I am very happy with there performance. The cases are just about fully formed all they need is the shoulders squared off. I think the hydro dies are a good idea one less firing on the case and you are not resizing the case one time. I'm going to try to build my own hydro die for my 22 dasher. I'll keep you posted.
