The only way to learn to "shoot where it's gonna be" is to practice.  A sling will free your hands.  Most anyone can learn to load a shotgun rapidly.  Clay pigeons, thrown by an assistant, provide good "moving targets" for practice.  Wear earmuffs and glasses when shooting.  In some situations, a rifle can do a job that a shotgun can't.  If you're careful to keep your firearm oiled.  Cleaned, the gun should last long enough for you to pass it on to your grandchildren.
