Typical driven pheasant I shoot, nothing below 20 yards tends to get shot at unless its a pricked bird. Your bred and butter birds are coming at 30 yards high and you might get a few get up a bit more each drive coming over at 45 yards 50 being about as good as you get. The shoot I went on where I found the birds high your bread and butter birds were 40 yards with the real high flyers getting up to 60 yards when the wind was favorable or they were driven off high ground. You man in the film is selectively choosing birds that look to be getting on 70 - 80 possibly more. What we might normal call a high bird 40 - 50 yards, is very different to the birds this man is shooting at.
