7.62, run&gun means just moving around a lot. Try a spot and if no action move.
Walk and hit locator call, when you hear a response determine in which direction and approx how far away and close the gap. Then set up and pull out the turkey call. Never let a bird know you are there, and if they do see you don't run after a bird!

Put them to bed means going out at the end of the day and trying to figure out where they are roosting. You aren't chasing them to their roost, you just wanna know what trees they are in so you can set up near there and call the following morning.

Personally I just make myself comfortable in a pop-up blind and spend the day. I'm only on a small piece of land so I set up where I see them feeding often and just call occasionally and wait. I've had both great seasons and disappointing ones doing this.

Good luck.
