I have hunted a good portion of South Carolina and Georgia, with the exception of the extreme upstate areas. There is a little bit of everything in shooting distance and open area around here. There are planted pine thickets and swamps in which visibility is measured in feet to beanfields and clear cuts that you can't see the end of. There is a fine gun maker fairly close to me that specializes in long range "beanfield" rifles.
I know the expanses of open ground are not in the same context as the west, but I have killed deer with shotguns and 00 buckshot at just a few yards to reaching out a few hundred yards with a 7mm mag.
