I wish I had a X peg to use when I was holding Dove shoots years ago. Everybody expected the most prime spot it seemed. I assigned spots most days, putting the better known shooters in spots that would get fewer birds knowing that they would kill just about all that came their way. The shooters who could not hit their ass with a spade, got spots which offered more action, knowing their hit percentage would be so low that it evened out. The only way to make them a bit more careful about shot selection was to limit them to two boxes of shells. After that they had to take the walk of shame back to get another box. And no more than one more box could be taken back into the field at a time. The walk of shame was what it became known as because with a lot of birds needing more than two boxes said you were a below average shot and after the third box it said you were really a bad shot. Some shooters could have used a truck load of shell while others could be done with a box or so shells expended.
