Regular water will not give you good data. You must use demineralized water with a wetting
agent and as you bring them to the same exact level you must weight them against there
original empty weight.
This is probably the most accurate method but it is very time consuming.
Weighing needs to take place when the brass is new,sized and trimed. after it has been fired,
sized,trimed and loaded many things will change the weight (Pressure is the main reason
and bullet weight, type of primer, powder charge ETC).
If you start with consistant brass weight, it should remain consistant through it's life as long as the same load is used in every piece of brass and in the same chamber.
The weight may change over time, but the brass will be consistant within the batch.
Even after all the sorting is done some fliers will happen. When this happens I mark the brass
and if that case throws another flier, It is discarded (Forever).
