Had one do that on Nov 30 2018. Three inches higher up and it would of taken off the jewels as it passed by as it was it took five stitches to pull things back together and the leg is still not healed up. In my case it sliced the leg open as it passed by but it did not implant. Broke into three pieces and found one piece about twenty feet from where I was standing still looking for one piece not sure where it landed. Lot of force running wild when they let go.
