Nah, use a little Duco Cement to hold the overshot wad in place. Works like a charm and leaves no residue. Just in case the uninitiated are following, one has to use wads 1-2 gauges larger with brass shells. Mag Tech sells them.
Also, it doesn’t hurt to put a paper strip around the shot. No leading.
