I purchased a sharpening stone from riverwalker76 and all I got were pieces of rubble. He would not refund the funds but instead informed me on 9-05 he would send out another rock of which has still not shown up as of yet. I did not wish to have another by looking at the first. He was banned on the cast boolits site. http://castboolits.gunloads.com/showthread.php?t=91754
Just a Heads Up.
