The proper initial move, however, is to get the muzzle moving with the target. Immediately thereafter, start the buttstock to your shoulder. If you start the stock to the shoulder first, the gun's muzzle will tend to dip downward, taking the muzzle away from the bird's flight path. Also, while you're making the initial move of the stock to the shoulder, the bird is increasing its separation from your gun's muzzle. Consequently, to connect you have to do more catching up than if your first move had been getting the muzzle toward the bird. Additionally, your swing will be herky-jerky, first down, then up, then to the bird's flight path. It's the exact opposite of the economy of movement for which we're striving.
