Love the guys replying who obviously have never used a scope on a turkey gun but they know what is best.................................it's not about distance it's about point of impact..............I have been using a scope for well over 10 years now, don't wear glasses, have no problems shooting hundreds of flying fowl yearly with a beaded shotgun and I don't push my guns range limits on turkeys. I would never go back to not having a scope on my turkey gun, I use a Bushnell trophy with the circle X reticle, love it, place the birds wattles in the circle no matter the distance (within my gun/choke/shell limitations) and it's dead turkey.
I was kinda the same were I didn't see the point in using a scope until I actually tried it and like I previously stated I would never turn back and totally recommend buying and scoping a dedicated turkey gun. To the OP do it and you will not regret it.
If you think a scope complicates things you might be the one who is simple.............
The whole patterning of gun/choke/shell comes down to precision and knowing what your guns limitations are. There is no doubt you can achieve better results from a scope over a beaded sight.
If you don't like using a scope that is totally fine but to look down on someone who does is just plain well...........simple..........
