Trap I am not certain of, but I do know that Todd Bender has some great videos for skeet.
I concur with CUSH, though. A good coach is the best route. I was fortunate to learn from my Dad and local folks, then had the honor of learning from John Satterwhite. The best shooting experience I could have imagined.
When learning from members at the club, and other clubs, take all the pointers that work for you and make it into your method of shooting clays.
You may want to try to obtain a copy of Trapshooting with D. Lee Braun. Both his Trap and Skeet books were excellent, especially for the day.
Good luck!
