This may sound like heresy, but turkey hunting as practiced here is rough shooting, blind or not, and as such means the gun will likely get some bonks, so for new, look at a Huglu with shorter bbl.'s and Full Choke screw-ins if you want a new double, and use any premium load of 36 grams of #6 shot. The main thing about successful turkey hunting is to get the bird within range, much more so than what it is being shot with. Lead number 6's will get the job done when the bird is within range. They are not migratory, so lead remains legal, and you don't need any more magic than that.
