As an FYI, I used range balls for this upgrade. Range balls are manufactured to be inexpensive (really cheap) and durable so my guess was that they would have a solid core. On a side note, I used some WD-40 when I tapped the threads just for fun and they turned out great.
As arvidj has pointed out, if the ball has a liquid core you will get more fun than you bargained for!
