RE: why hasn't all Pa gone shotgun only
Proline,
My home county of York is heavily cultivated with your above mentioned crops. The ground is rolly just like Ohio. There is a heavy population of people and deer. A favorite pastime of the local hunters is "field shooting" which consists of shooting at running deer out to about 300 yards. They can actually kill deer this way with a rifle, but they sure as heck could not do it with a shotgun. A shotgun is a much more limited weapon than a centerfire. I would compare it to a muzzle loader for balistics.
If you see them pass shotgun only regulations in the people populated counties, I would bet my rifle that they would get deer just as big as Ohio with the same kill figures.
