One of the best turkey hunters I've had the privilege of hunting with used an old Remington 1100, with a modified fixed choke barrel, that had very little finish left on it. The wood was beaten-up pretty badly as well. He used that gun for everything, waterfowl, squirrels, rabbits, deer with slugs and of course turkeys. It had a long barrel, maybe 28", I'm not sure and both he and the gun are gone, so I'll never know.
That old gun in his hands accounted for very many turkeys while we hunted together and had before I ever met him.
Thanks,
Clark
