I saw some of the mounting on lovemywoods steel targets. I have always used chain in the past for steel but i saw your horse mat idea and thought that might better for rifle because IF you hit the chain directly with a big enough/fast enough rifle round you can cut the chain. How does the horse mat hold up over time of being shot? But i guess my main concern is ...is the ring of the steel "muted" or "muffled" by the rubber horse mat? I would almost think it would be but i wasn't sure. Thanks in advance!
