My grandfather passed awhile back and my dad decided to give me his old single shot 12 ga. It's a h&r full choke . First gun i ever turkey hunted with. I haven't got to pattern it yet but i have decided I'm going to kill a bird or two with it this season. Was wondering if anybody had any suggestions on some shells to try. After the season I'm going to send it off and have it set up for screw in chokes and make it a dedicated turkey gun. Anyone know of a good place to send the barrel to, that they have had experience with and does good work.
