my box says ''Winchester Double XX copperplated lead shot turkey loads ''.......12ga,-3inch-mag-2oz-6shot , 10 shotgun shells......sticker says $6.99
I still have them because I use the Federals out of a box just like the one in the photo..
Winchester used to make a XX or Super X with copper plated shot called Lubaloy shot, made for waterfowl hunting. I got hold of a case of 3" #6 shells in 1977 or so from a Winchester sales rep. Not sure when they quit making them before that. That was a turkey killing load.
