I have hunted Eastern species most of my life and they are said to be one of the most wary species of turkey. Best advice I ever got was the "set up" was the most important aspect of calling in a bird. Hard to explain but I try my best to be uphill from the bird and along a route they typically travel. I call until I know the bird is answering me and coming then I switch to a soft yelps and clucks. Know your shotgun/load capabilities and practice with it every year. Preseason scouting is important.... go in at daylight and listen. I use a crow call, owl and hawk calls to help me locate and move in on a gobbler. Every day in season is a new day and only experience will increase your odds of consistent success. Good luck.
