Pick up the book "Shotgunning: The Art and the Science," by Bob Brister. In addition to actually getting out there and busting some clays, maybe even with an instructor, it is a great read and great way to get the fundamentals on wingshooting. In addition to in person lessons and practice, I have always found it important to first mentally understand the principals. This book does just that. Brister also provides a wealth of knowledge on many other aspects of shotgunning. It's a fun book, and so is shotgunning!
