Don't know about that range, but I have had it come back at me a couple of times at HP Shooting Ctr. in McHenry years ago.
I think it's a good idea to use a heavy, sizable cardboard backer that you can attach targets to. It won't solve all the problems, but it can act as somewhat of a shield. I think the jackets that came back at me, were from someone else's lane, btw. I've seen it draw blood on a couple of people before.
