They're not ACTIV.
Sullivan Variwad at first look. They made several and I don't have any left.
The only other wad that I can think of that it might be is WANDA. They made a 2-piece wad, but they came as a 3-piece set. An overshot wad was included because a WANDA hull wasn't crimpable. (Is 'crimpable" a word)? If it's a WANDA, the only reloading data I ever saw for them was in WANDA hulls.
