For sure, never seen anything like that before. Light charge, bullet seated way deep, and lots of lube I guess? I tried lubing over the ball one time in my life, after I got my first C&B revolver. I says to myself I says: "that's enough of that". This is sure an extreme example of way way way way way way way too much lube.
I've never had dry wads stick to a ball, but for sure waxed wads. If the gun stays loaded long enough, like months, the wonder wads will stick. The lube on them seems to interact with lead. If you put wonder wads and balls together in a container, the balls get heavily corroded or oxidized pretty soon.
