I believe that the only way to get truly good brass is to fireform in on a tigh crush-fit in your own chamber.
If Jackie doesn't get back to you and if you're interested in another take.....I've a 2.5-3hr video series in which I "recreate" or attempt to follow Jackie's lead and succeed greatly in making absolutely spectacular cases.
I believe Jackie's method to be far superior to all others with hydro-formed cases like DJ's being second best of maybe 6-8 methods. Jackie's method solves ALL the problems, neatly.
