Nice job never used buckshot for any hunting. Have some to play with. Glad all worked out. I got mine last Sunday the old fashion way, stalking the same as you. Got mine a little farther with my old .22-250.
No stalking for me. It came to me. Like most turkeys I've seen in the fall, they don't much care if there's a deer hunter in orange in a blind or on a stand. Sometimes, they'll forage right up to near you.
I did notice three of the group that went to my left ended up going uphill out of the bottom area I was in and settled in a clearcut area. That area is nearly impenetrable with small pines, thick blackberries, devils walkingstick, and every other thing that growns a thorn. That area make a WWI battlefield covered in barbwire look like a kiddie's playground.
