I don't know if they ever did anything with it, but Winchester, in the late 70's talked about indoor ranges...be interesting to see their plans, if any.I have recently seen some figures on special-use buildings, like for tennis or golf, and it is almost impossible to make a proft from this type of special-use building. However, if you could figure-out how to hang a shooting range within a dome, used for golf, soccer and the like, you would have a ready market. Further, there are still a lot of empty warehouses around the country.
