6000 bbs at waly mart for less than $10.00 cheep shooting. Use very light bands and a pouch that has a magnet in it. Very quiet and dos not look like a gun to get the tree huggers attention.Dude Yarhei, why would you wanna use BB ammo for sling shot? You might as well get some cool BB guns for yourself instead right?
My dad used to make us a toy when we were kids that was made out of spark plug halves, each end would be wrapped with clothes hanger which would then be used for the handle. Match head were then put in the middle, and you'd smack it on the concrete and it would go off like a .22. (I think I remember that right...lol)Porcelain chips or spark plug halves...they penetrate glass easily
