Man I can't say enough about having that datum dial. Or even the Hornady one would be good. It is so eye opening to see exactly what the dies are doing to the brass. The last 3 calibers I have sized have been very different experiences. The 243 Hornady die wasn't sizing enough but the lee did, and I had to have maximum amount of cam over. 338-06 I had to have the sizing die backed off away from the shell holder or else it was sizing way too much. The 35 whelen I had to turn the die about a 16th of a turn past the shell holder for barely any cam over. I'm going to say, after using it, that it is a must have piece of equipment on the loading bench.
