Neck forming tool

[abunaitoo]

Is there a neck forming tool/die that uses bushings to gradually reduce the neck?????
I was think that a neck size bushing, or something like it, could be used.
It would size a little at a time, so not to fold/crinkle/smash the brass.
I have made different pull trough sizers to open up necks.
Cut down on my split neck to almost nothing.
I know they make forming die sets.
But kind of expensive and caliber specific.
I wonder if the NOE sizing bushings would work????

A guy named Bruce Lambert used to make a set of necking bushings and a die body.
He posts at Accurate Reloading how ever per his posts he quit making the bushing sets years ago.
He did provide photos of cases that he necked down in steps.
