Wish I could help you more. It's very complicated.
Here are the Pa., regs:

You didn't particularly specify spring or fall but I will draw distinctions.
Spring:
Mating season. Lovesick gobblers. Called with various devices. The major concern is location, terrain, availability, heavily wooded, some open meadow. In wooded areas it's one step next to impossible to succeed. They are too smart. Eyesight too good. Farmers fields are absolutely loaded then when corn or grain is available. They like to eat. I've seen over a hundred in a field. The trick is to get the farmers permission and NOT shoot his cattle.
In some areas people feed them. They become acclimated and unafraid. In fact there are cases of them attacking, roosting on roof tops and cars. Some Towns have them walking in the streets in great flocks, as many as 30 birds.
How to hunt. Pick a good spot and wait. Pre-scouting is essential. They don't tell time.
Fall hunting:
After the breeding season the gobblers group up as do the hens/jennys. Again location is all important. The technique is to "bust" the flock, spread them out. They soon begin calling to re-group. Chase down individuals. It's really tough to get close. Some use dogs. Hide them in a sack until time to "bust" the flock. They are smart and certainly a challenge.
I have often seen flocks of gobblers in the winter, out of season, completely unafraid of me, 50 feet away, so long as I was in my vehicle moving slowly and even stopped but just step out and its adios.
Just another tip. Turkey guides. They are successful, and it seems that as usual most have the best terrain locked up, with owner agreements, and inaccessible to the average Joe.
