Copper versus lead versus lead free pellets in .22

Lead. Friend or Fo? Can copper pellets ever substitute lead pellets, or do we need to look at lead free pellets. I had the chance to test all three, Part I will be all about the 30m results, I look at optimal speed and the different groupings and observations. In Part II I will be stretching the legs out to 60m.
