I have my doubts on the ball improving expansion. My guess would be that one would see less expansion to poor performance but in experimental work; one moves in steps. Ron found a way to improve BC. Step one. One really need a pointed collapsing medium in that big cavity that would add to flight profile but collapse back to expose the hp on a rib shot. We can look to Hornady and others for the design shape. Bubba has to work with what he has.
The Hammer bullets shed the petals rather quickly which leads me to believe that expansion will be fine
I got banned on another web site for a debate that happened on this site. That's a first
