It pains me to say, but on some estate videos, Daves skill surpass their ability to deliver distant enough birds.
I hate seeing shots that are at birds 3 pegs down.
Yikes! Sounds to me like there's less distance between pegs than at the driven shoots in which I've participated (none of which emphasized really tall birds). Every now and then--especially if the gun to your R or L is a friend--a bit of friendly "poaching" is more or less expected. But I can't imagine shooting at a bird 2 pegs away, let alone 3.
