The shooter said he was dead on at 200.
He didn't say he was dead on at 200 yards.
He said it was easy to get on at 100 yards and even 200 yards.
It was easy to get on at 100 yards and even 200 yards !!
At 200 yards you would only be 2"- 2.5" off with a 10mph wind. Very easy to compensate for. At 300 yards you get 5.5 - 6 inches off and is much more noticible and if the wind insn't a steady 10 mph,much more dificult to compensate for.
Of course it could be him but my money is on the wind.
