GWS, I would be using a proper die for these, as well, if I CH4D hadn't had their entire inventory of .44 swaging dies and parts bought out by a single person. ...and/or if that person would get their own production run finished, instead of just jabbering about it all the time, and blaming his suppliers for delays.
I would really like to be putting a proper ogive on these bullets. It would eliminate at least half of the problems that are created by trying to work with the sharp, short nose profile the 7x57 die provides.
But, until some one makes a reasonably priced die available, I have to keep working with what I've got.
