It looks like you just answered Ty's question.
I'm guessing the symmetry of your shooter combined with the smoothness of the outer surface of the boulder, unlike a baseball, is allowing you to shoot very consistently.

One thing to note is that you are putting a good amount of side loading on these gearboxes when you cantilever the wheel as shown. This is both adding extra resistance which could be why their smoking at the end. If you watch the video closely this flex in the system is also introducing an upward component on the launch. I would suggest possibly supporting the shaft end to reduce side loading and improve efficiency of launch.
