I'm thinking about trying the Winchester Long Beard XR 2 3/4 ", 1 1/4 oz. 5 shot loads in my favorite turkey gun. It's a J. Stevens Arms Co. 12 ga. single shot 2 3/4 " hammer type probably manufactured in the 1930s or 1940s. I usually shoot 1 1/4 oz loads in it. Has anyone tried that 12 ga. 2 3/4" load? What do you think about it in that old gun? I'm thinking about buying a box, tying the gun to a tree and pulling the trigger with a string from around the barn corner. I guess I could take it to my gunsmith buddy for his opinion but figured I'd ask here first. Any advice or opinions?
