If it was a one gun that does it all, a Remington 1100, with choke tubes.
Quail, Pheasant, Ruffed Grouse, Sharptails, Ducks, Turkey, Skeet, Trap, Sporting Clays, etc. Get a rifled barrel and it will meet most deer hunting needs as well. I know from experience. I've used one successfully for all of those pursuits.
Ideal for any? - possibly Pheasants and Skeet, but that'as why we all have more than one shotgun.
