I've used the Lee also but I seem to get better results using bushings. I fire form my brass to get chamber size and order the bushing (Redding)accordingly to get just the right neck tension. Then I have what I want -consistency. I anneal after 5-6 firings so necks remain soft and lose their memory to avoid uneven neck tensions. I use the Lee in my auto loaders.
Interesting! My experience with Lee neck dies and the Redding neck die with bushings was the opposite.
Using my RCBS case gizmo to check alignment, I found the Lee neck collet die gave just as good alignment as the Redding bushing die, and was not sensitive to neck thickness as the Redding neck bushing die was.
I disliked being forced to turn necks, or to get a different bushing for different brands of brass. So, I kept the Lee die, and sold the Redding neck die and all its bushings.
