The most common distance for me to shoot mine at is 400m. They are all lightly tuned and I shoot an 11" gong at that range, off the irons.
I don't really formally test my stuff, but I would say all my tuned guns are doing about 2 moa at 400m.
But then I have also shot 2" groups at 100 yards with a stock gun. My groups at 100 yards after tuning are always below 2".
