RE: what gun would you pick????
Like a post above I say you haven't said specifically what game or situations you mean when you say "to hunt with".
So I would assume that you mean "everything that I now hunt or may hunt in the future". In that case you left out my best choice, a Rem. 1100 shot gun with two diffrent barrels. One would be a smooth bore tube with a changable choke system for all bird and some small game applications. The other barrel would be a rifled slug barrel with a low power variable scope. It would be an passable big game gun out to about 100yards or a little more (with sabot loads).
