We only have one moving target on the trail walk. We shoot it with our smoke poles. It's a Canada goose and gets up a good head of steam by the time you see it. The shot must be taken within about 3 seconds. Good sport, but not very difficult. Even the women hit it, those who do some clay bird shooting, that is. It's about a 45 yard shot, broadside. Most hits are in the body as the head is the aiming point, but it does run on a bit of an angle.
Practise is necessary for sure.
