The easiest way to do this is to fill to the brim with a very fine gunpowder. I use WCC680 which is as fine as salt. Tap the case to ensure it is well packed. Then just dump into another case with a funnel. Tap and see if it fills to the same level. You can quickly compare 50 cases without the mess of water. More then accurate enough way to measure comparative volumes. I will cull any case that has a difference in 'height' of 1/8" in a magnum case and less in something like a 308.You will find that most cases come out with identical volumes.
I don't weigh cases as the tolerance you are measuring is within the variations in the machining of the extractor groove. How important is that? Weighing was a quick and easy method to try and identify cases of differing volume. However, it is not a reliable method. Just find some brass from the same lot that varies in weight, then compare volumes. I bet the volumes are near identical. I figure, if I want to compare case volumes, compare case volumes.
