I have hunted wild turkeys often and to a point I even shot a banded one with a nice beard once.
The Rio's we were hunting down there were a little harder to call in, and spooked pretty easy, but they saw "pressure" in their territory from man and beast, so that might have made a difference as well.
It was funny at one point when we were calling them through tall grass/brush, and you would see them stick their head up for a few seconds well out of range, and look around before ducking back down and coming closer.
I got lucky during that hunt when the guide called in two toms that broke the grass line close enough, then got a good look at each other and started fighting, and when they start fighting, they don't give a crap about anything else. I shot one as my limit, and the other one kept kicking his ass after he was dead.
