Welcome to the addiction turkey hunting is a blast. As for as ammo you will want to try different shells to see what shoots best out of your gun. I like to use smaller shot like 5 or 6. For calls there area a lot of them and each style works. I like mouth and slate calls the most. There are tons of YouTube videos that give tutorials on callin that are very helpful. I would also add a crow call and owl hooter to the collection. If you are going to be hunting with a gun don't be afraid to be mobile either
