Late entry offered FWIW.
Prior to spending serious coin on a shooting lesson/instructor before the shooter can appreciate what he is being taught, consider some VHS viewing.
Beg, borrow or buy the VHS "Wingshooting" by Jack Mitchell and Michael McIntosh. The late Jack Mitchell's plain English "Cathy, I want you to do this' type of instruction is the best you'll see anywhere. I like the way Mitchell and MM compliment and play off each other. This is "THE" VHS you want.
A second recommended VHS is a two tape set - "The Art of Shooting Flying" by Bryan Bilinski and Tom Huggler. Not as engaging as the "Mitchell/McIntosh and lady student shooter" VHS, and a bit repetitive, but it covers all the bases.
Bilinski is "Fieldsport Michigan" and has his act together.
I think if your new shooter sees what "the final product" should look like on the home screen, it will make his later "hands on' instruction more meaningful and effective.
