Without actually seeing the balls, it is hard to say what could be causing the consistent lines. Try doing what I said above about making sure that your molds are absolutely clean, well smoked and that the mold and lead are both the correct temperature. Also, I don't know if you are using a bottom pour pot or a ladle to fill your mold. In either case, you want to quickly fill your mold and leave a small puddle on top of the sprue plate. Filling the mold slowly can sometimes cause lines or wrinkles depending on how you do it. Clean, hot mold, smoked cavities, lead of the proper casting temperature and quickly filling the mold with a puddle on top should correct the problem.
