Kona,
A lot of guys don't have wide open area to shoot (their own range), and a lot of ranges have fixed target holders. The ranges typically have rules stating that you can shoot at targets on the backers only, which means you can NOT set up targets on the ground, like a gong, or steel plate. It sucks, because shooting gongs, clay birds, and golf balls at long range is awesome! Most ranges won't let you set the stuff up for liability reasons. (They want the bullets to impact the mounds, not hitting the ground and potentially deflecting into something?).
Many people have no need for steel targets, or have no place to use them. That's probably why you're not getting many responses.
