I use a cup warmer. I put 5 on the warmer. When begins to get warm enough I put my thumb in the shot cup and push down on the wad over a 2" trailer ball. After I take the first one off the warmer I replace one on the next one I remove. I just rotate one at a time on the 5 wads. Only takes about 2 seconds per wad once you get a rather going.
