I don't know about other parts of the country, but in Virginia we have a good turkey population. This allows for fall turkey hunting, including hens. We walk game trails and fire trails, and search for scratching, especially in areas of white oaks and other trees with nuts. It's difficult to get within shotgun range, under these circumstances. Now spring time hunting is a different ball game. Only gobblers are allowed and you would be setting and calling. Although tradition calls for a shotgun, a rifle is allowed in areas where you are allowed to use rifles. This would be the more mountainous parts of the state.
Hunter safety course is a requirement, in Va. but real safety is placed squarely upon the shoulders of hunters. I would never use decoys on public land, and am very cautious as to where they are placed on private land. The advantage of a muzzle loading rifle, is, you can set up in a more open environment, and be farther away from decoys, due to the extra range, and enjoy a more traditional method of hunting.
