Unless you get sub 1/2 MOA groups with any batch of cases, there's no need to sort them by weight, water capacity or powder capacity. Just keep each batch/lot separate and that'll do just fine. The heavier ones may well need a grain less powder to keep peak pressure the same, but even that should not effect accuracy in any way.

Weighing cases to a 1% spread is good enough for even the very best accuracy. How much stuff cases hold will vary even with the same case depending on its shape and whether its been fired or not.
