Hopefully this helps someone:

Just finished neck turning and weight sorting some ADG brass for the 7 Sherman Short.

The attached image shows the case weights of this admittedly small sample. The extreme spread was 2.7gr. 175, or approximately 87.5% of cases fell within 2 gr of each other, which is the level to which I sort brass. 72% were within 1.5 gr of each other and 54% were within 1 gr. Case necks tapered from between .0160 and .0185 at the shoulder junction to .0145 and .0140 at the case mouth. Turning did not seem to be necessary but I skimmed them all to .0140 anyways, which cleaned up approximately 65-95% of each neck.
