Since I last posted in this thread I loaded the other thirty pieces, but before I assembled those I weighed every one of them. There were two weight classes in this batch of brass, one at 176-177 grains and another at 179-180 grains. Why am I not saying the cases weighed 178 grains, +/-2 grains and that's not bad for non-Lapua class stuff? It's because the distribution was clustered in the stated bands, nothing much in the middle. Maybe there were two lots mixed in this bulk pack brass from Midway. That's not the problem though.
This evening I did take some time to measure the necks with my tubing micrometer and they are a disappointment. The majority of them are .015" thick on one side and .013" thick on the other. It looks like my neck turning gear will get a workout.
