A friend has taken three turkeys so far with whatever 1 oz load of #5 shot she had left over from pheasant season. She hasn't fired at a bird more than 25 yards away so the load used really didn't matter.

Which is the key- the closer the bird, the less important ammo becomes. We hunt in the woods where visibility is limited. Basically, if one can see a bird, it is in range. Typical turkey chokes and ammo is not an advantage and often a disadvantage in these conditions. I used my old lead waterfowl loads for many years with no problems. I might break some out again if I decide to use my dad's A-5 on a turkey.
