Spring turkey with a muzzle loading rifle is legal in Georgia, and the only way I've ever hunted them. As far as load goes, shoot what you shoot best. Ideally I dream of Thomas coming straight at me, and aim at the top of the "v"in the breast, where above that is neck. Never seems to work out that way. But I would rather miss cleanly than have a bird full of pellets or shot. I would suggest snap shooting off hand. I'm sure you'll be in some kind of blind so practice that way. Then practice some more. They rarely stay still for long. But Thomas can be as stupid as a buck when he thinks a hens around. Just triple check the regs for where you're hunting. The DNR is serious as a stroke when it comes to turkey in Ga. You can loose everything and have to buy it back at their auction. Seen it done over an honest mistake. You never can tell when you've harvested one with a microchip in it's wing, but they can. Good luck!
