Some guns shoot better than others... I have a 870 with a 26" barrel and with a Remington Ventilator choke and Win XX 2oz #5's will put around 15 lethal brain and neck vertebra hits at 40 yards... I was working a gobbler one spring morning for about a hour and a half. He would come in just over a rise about 20-30 yards away and then drift off to about 75-100 yards gobbling the whole time but would not crest ridge... Anyhow after him coming in and fading away 20 different times I was really getting frustrated... The next thing you know I hear him gobble closer than he ever was so I got ready... I seen his head pop up just over the rise... I let him have it... I paced it off and it was about 46 yards... I bought a new turkey gun this last spring(870 SP 3.5" mag) and with Win HV #4's it will put 15-20 hits in the vitals at 42 yards... I killed one at 56 paces this past may
I would not recomend shotting at those distances unless you really know your gun
