Stopping the swing with the shotgun is one of the most common reasons for missing ducks and geese. You must follow through with your shot! Try stopping your club when hitting golf ball, and see what happens. This wrecks your timing and coordination. The same thing happens when you stop swinging your shotgun. Keep the barrel moving after firing. Having good follow-through is the proper conclusion to any athletic effort, be it shooting at a duck, swinging a golf club or throwing a ball.
