I've seen George do this stuff at a Game Fair and make no mistake he hits clays at extraordinary distances; the day I saw him was also stinking hot and very still FWIW.
I never saw a surveyors tape though, so claims as to exact yardages don't stack up; as my old Black Country engineering mentor used to say, "It'll all pass if you don't test it".
As regards the very high pheasant discussion, I think Salopian knows many of the high drives round here and the artillery some folks employ. IMO the heights some birds are fired at are excessive and unrealistic; I base that premise on the number of shots fired to clean kills. It isn't great to see and I'm sure that colours his opinion as it does mine.
I'm the guy with the three retrievers 400 yards behind the line and I'm not there because all the birds are dead round the pegs. Me and The Boys, we see it all.
Nuff said.

As regards high pheasant shooting at extreme ranges, I still say it has NOTHING to do with exhibition clay target shooting.
You go George.
