I don't do a lot of shotgun pattern testing, but must say I have killed plenty of turkeys with pheasant loads (usually 2 3/4 inch #6 shot) out of both 20 and 12 gauges with regular chokes. Ranges from 5 to 40 yards. Unless you're taking shots at 50 or so yards, all that crazy turkey gadget stuff is worthless IMO, especially the "heavy turkey loads".
