Bear Creek Arsenal Complete Uppers

I had terrible accuracy for the first few dozen rounds. I thought it was the crappy Wolf ammo. I switched to the hunting ammo and the groups got very good. Then going back to Wolf, those are reasonably accurate now too. I've never believed in break-in, but something happened. Could be any combo of cleanings and such too.

What ammo are you using? I'm also finding that one high end round is far better than another.
