Just buy the Lapua brass and stop wasting time sorting and have a beer or scotch by the fire pit. Much better use of your time and effort.A lot of guys weight-sort brass. A lot of guys don't.
The premise, as Don suggests, is that weighing brass is a simple, quick way to figure out volume differences. A premise that many of us feel has never been proven with any consistency.
What you might do is take that light batch and actually measure the volume in, say, five cases. Then do that for the heavy batch.
If you see a correlation between weight and volume, there's your answer. And if you don't, there's your other answer.
