RE: Is Skeet Shooting good practice?
Anytime you can get out and shoot the gun you're going to use in the field is great practice for when you're hunting.
Sporting clays is going to be your most closely matched shooting sport to the types of shots that you are going to see in the field. There's also a thing called '5 Stand' if you've heard of it....which is basically a lazy man's Sporting Clays and is equally as suited to getting you prepared for the types of shots you'll be taking in the field. It's almost a combination of SC and Skeet.
Skeet alone is a great time once you get into it, but probably isn't as centered around hunting as much as proper mechanics of shooting. Proper gun mount, learning proper swing, and practicing sustained lead are all things that can be enhanced by getting good at skeet.
