I have no build info to add, only load info, in researching for a 6.5 build I just had completed, did run across some data on the 6.5 Creedmoor, passed that info to a buddy that has one, he's getting ragged hole accuracy and over 2800 fps with 143gr ELD's and Winchester 6.5 Sta-Ball powder, the powder is said to be extremely temp stable, and from my lack of knowledge on the cartridge, 2800 with a 143 in the Creedmoor sounds like a very good place to be.
Good luck and have fun with your build.
Gunner, I have two cans of StaBALL and want to try it with 140 ELD-M. I've read reports that the ELD-M bullets do as well if not better on WT's and such than the ELD-X 143's. I'm sure the harder X version would be better on bigger critters.
