Hi Alan,
 
I had a similar problem which I tracked down to axial distortion of the split die in the die stock caused by the screw opening up the die and twising each half in a different diirection. A bit like a spring washer.
 
It was a poor quality 'cast' die stock witha poor seat for the die and rough ends on the adjusting screws.
 
A decent stock resolved the issue.
 
I have also found, like AndyP that some dies do seem to cut better threads when turned round!
