Wonder how much time it took for him to get that zeroed in. I wonder if the EOTECH can even adjust for that kind of drop. If I remember correctly a standard high velocity .22LR drops something like 40 inches at 200 yards and triples to 120 inches at 300 yards. Sure he didn't have a buddy with a .223 somewhere down the line shooting at his target?
But seriously, that is some awesome shooting.
