"The WAA12R, commonly called the Winchester red wad, was designed for 1-1/8 ounce loads in the Winchester paper case. It is generally too short for 1-1/8 ounce loads in the typical plastic case and is used mostly for 1-1/4 to 1-1/2 ounce field loads in plastic cases."
FITASC, I think you explained my accidental success which occurred many years ago when I had a bag of "red" wads and loaded them up in a plastic AA shell with 1.25oz of #4 for Turkey and bagged one. I still have the load in inventory, and I still have the wads but now I can feel more legitimate with their use!!
For 1-1/8 I've been using CB-1118-12 with more knowledgeable comfort, but I came across a Hogdon site that listed substitution wads which triggered my question.
