I've heard that Measuring helps solve that problem 8)
Size a few cases then measure the ID's. Similar ID's will pretty much marginalize the issue of uneven annealing. Change mandrel until you get the desired ID for the neck tension you desire.
As I see it, the LCD is a perfect solution for those who don't neck turn or want to use an expander (mandrel or ball) in their process.
