Anton,
I got double that from my first 50 pieces but I was just playing around with multiple powders and bullets so some were warm others were mild loads. Hornady 6.5CM brass is pretty decent stuff IMO. I did anneal mine three times and loaded it three/four times in between. No split necks but now primers are very loose in about half of them.
I picked up 100 pieces of the new Nosler 6.5 Creedmoor(Norma stuff) and just randomly weighed 10 cases and they were amazingly consistent..IIRC all weighed the same except two and they varied less than .5gr. On the other hand the Hornady varied almost 3.0 gr's
I run a AR10 Creedmoor so I will save the Nosler for a special occassion.
