Brass weigting yes or no?

Do you guys separate brass by weight or no? Well a few months ago I have separated a batch of 350pcs of DAG .300wm cases. I wasn't really picky I just weighted all at 1gr and then put them in 3 groups so there are most 3gr differences between them. Those that were really different went away... Now I have loaded one of the three batches with the same recipe that I published in the load database. It was all the same just the cases DAG(sorted by weight) instead of RWS(not sorted). The result was that my ES lowered from 21m/s to 8m/s...

I always sort my brass by the weight. Usually divided to groups by 1gr. The most accurate cases fom all I use are the Lapua in 6,5x47 Lapua. 600 cases, two groups of two different lots. Every lot still inside the 1gr tolerance, the difference between two lots is about 2gr.
