For those interested, I just checked 10 of the recent batch of Hornady Creedmoor brass I purchased a few months ago. The necks ALL varied less than .001" in thickness, which is excellent. The lightest case weighed 151.0 grains and the heaviest 152.6, with a standard deviation of .53, also very good. This is comparable to the consistency of Lapua brass, and I might have to buy some more!
