I have taken turkeys with a Winchester Super X 2, 31/2 inch and 3 inch 12 gauge, Savage sxs, 2 3/4 inch 12 ga, Remington 870 2 3/4 12 ga and my Ruger Red Label 3 inch 12 ga. All were tolerable except the 31/2 inch shell. I have fired exactly 1 of those and promptly got a mild headache. I can now pass the remainder of that box to my sons upon my death. I will hunt this spring with one of my 20 gauges. I highly recommend anything other than a 3 1/2 shell.
