Headaches, I usually get those from banging my head against the wall, but the pill bottle is empty and filled with little lead BB's that came extra with the dies for the star. I Like to re-use stuff I can get for free, you should see my garage, it looks like I run a Deli Salad Factory from all the plastic cantainers I get from the local grocerey store, they may great storage for brass and other stuff. As far as overengineering goes, I am not sure about that but it works for me!!!!! I just got the Co/Ax and so far love it!!!!
