Took mine to 600 yards this afternoon. Dialed in 10 MOA correction from a 250 yd zero, (per the Hornady ballistics calculator) and fired a 5 shot group. Load was 120 Amax factory ammo.

There was heavy mirage boil up and leaning right,which might have affected things but I just shot throughout it. I got what you see below on that 6" dot. Seemed to me the scope tracked pretty well.
