If they vary by as much as 2 grains in actual weight then the diffrrence in bore time may be enough to account for the poor grouping. Stack on top of that the other possible problems and I might just use those for case forming or a really close range bullet.

Bullet overall length on this batch I have varies in a sample of about 50 I measured for this reply from .593" to .626". When I tried to sort into groups by length earlier I had an ES of .040".
