The gun I'd like the most is my Dad's Mossberg 500 20ga. I remember how happy he was with that gun. He got good enough to be able to take a limit of doves in less than a box of shells. I 'bird-dogged' many a day for him and that shotgun. I even watched him drop a bird and catch it before hitting the ground. My brother has it, but doesn't hunt much...

As far as guns from writers, Shoemakers 458 Win, Barsness mauser 338 Win, and Page's 7mm Mag would do it for me.
