My first shotgun was a Winchester Model 12 20 guage with a 21 inch full choke barrel. I used it for everything....squirrels, rabbits, quail, doves, and even killed a deer with it, although it was not an accurate slug gun. It was my only shotgun for a good many years while I was growing up, and for a few years after I was married. It finally just wore out and wouldn't function properly, even after a gunsmith had worked it over. I sure loved that little gun, and it's one of those I wish I had back.
