You must develope a good consistent gun mount andgood fundamentals.
I would suggest finding a skeet range and shoot that low gun. After you can consistenly brake a 22 or better everytime then see if you can get permission to move back to the fence. This will give you a bit longer shot. When you got that down you can graduate to sporting clays.
It takes time and work to become an accomplished wingshot. Even those that make it look easy missed targets and game when first starting out until they honed thier skills. Work on you basics and in waterfowling where and how to place decoys , when and how to call (contrary to those with contest aspirations 3 basic calls is all you need to know) and buy best decoys you can afford. A 1/2 dozen quality dekes will outdraw a dozen or more cheapo's. Forget aboutall those 50 yard + claims. Most hunters are terrible judging distance and for those that shot beyond 45 yards I'll gaurantee for evey 1 they kill cleanly 3 or 4 fly away to die at a later.
