Buy a launcher and find some land.
The launcher and clays are very inexpensive.
The only advive I can give is.....dont aim......lead the clay and learn when to pull the trigger. With proper timing you can get 7-8 out of 10 within a few hours. Clay shooting isnt very difficult to get good at......its all timing.
Soon you'll be shooting 2 clays at once......then 3......then 4.
Its a fun hobby.
