Lots of good advice here from folks who have been there. As you already know, be careful what you read, especially from magazine articles authored by folks you don't know are experienced hunters. There are a lot of armchair experts out there.
Case in Point: It was the spring of 1978. I was just out of school and a forester at Clark State Forest in Southern Indiana. I had never turkey hunted. We had turkeys on the forest I helped manage. I taught myself to call using a 45 record and a tape recorder -- listen, call, record, play back -- diaphraghm call. No one had killed a turkey with a bow in modern times in Indiana at that time.
I read what I could find about bowhunting turkeys. This was the advice I gleaned from reading:
1. Learn to call
2. Bowhunters should master the diaphragm (hands free)
3. You cannot move in in the presence of turkeys.
4. Shoot low poundage with something on the broadhead to impede pass-through.
To shorten this story. During 6 AM hunts I had 5 toms within bow range (inside 20 yards). I never took a shot because I was hiding behind large trees and I didn't dare move (the advice) in a turkey's presence. The birds were always on the other side of the tree. One morning, my last chance, two birds (Tom and Jake) started to move off from about 15 yards. I decided to leave the tree and sneak towards them (to keep up). I squatted and moved ever so slowly. To this day I don't know why I didn't just toss the book-learning, and shoot when I was free from the tree -- the birds never did spook!
It took another 3-4 years before someone finally killed a turkey with a bow. It wasn't me. I had moved to the South Bend, IN area by then and there were no turkeys. Of course in those days biologists were taught (wrongly-by professors who didn't hunt) turkeys require unbroken tracts of forest at least 10,000 acres in size to do well....duh.
