Our range is in the desert and frequently wind is a problem with targets. A member came up with using a fairly big tire, ie: 33X15 or so. He drilled two holes one on each side completely through the tire; tire laying flat,and target frame supports placed through the holes. It seems to work well. Is this a safe use? It's fairly recent, but I don't see any bullet holes in the tire. Can the bullets bounce back? What about .22 rounds? As I said, there have been no problems...but..?
