Get a melon baller they come in various sizes and should give you nice uniform clay shot.For the life of me i don't understand why you need lead except for trying to kill something. You mean to tell me slingshot shooting can't be fun or accurate without using lead?????
I will buy lead for hunting only. Or killing tough varmints like raccoons or ground hogs.
For fun, however, no lead for me. In fact, I am gonna roll my own clay balls for target shooting. Very eco-friendly. It may not be tournament accurate, but I don't care. Bet I will still have mucho fun shooting it as long as I match my bands to the weight. Maybe I can even find a way to make them tournament accurate?
My point: lead for killing only.
