I agree with MnOutdoors in that it sounds like everything is going as expected as it pertains to turkey hunting. I hunt in south Georgia occasionally, which isn't too dissimilar from the type of woods and birds that you're hunting, and I can confidently say that those are some of the harder birds I've hunted. Definitely less vocal as well. I'd say that the one thing that helped me be more productive down there was not overdoing it with the calling. Also, I love runnin and gunnin, and I found that it simply didn't work down there. Those birds are very wary. My best luck has been when I made myself sit down and shut up with maybe an occasional yelp or purr thrown in to break the monotony. Good luck!
