All I can suggest is keep looking around.
I'm in a similar situation. West of town is a huge swath of land owned by the Plum Creek timber company that is run by the Fish & Game. Due to slob shooters, as others have mentioned before, the area is now closed to target shooting.
East of town was my second shooting area, which was Plum Creek but recently sold to the state, Forest Service, and the Nature Conservancy. Went out there to do some shooting last month to find a big sign stating that the area was closed to target shooting, camping, and off-road vehicles. I'm hoping this was only due to the fire danger and not a permanent closure, but only time will tell :idunno:
There are two ranges in the area, I can't afford the private one and the public one doesn't allow BP. On top of that, its a 45 minute drive and I don't feel like paying $5 each time to sit shoulder-to-shoulder with folks sighting in their rifles when I'm out shooting for fun.
On the bright side, when I move next year I will have unlimited access to my father-in-law's personal 300 yard range behind the barn, so that removes most of my concerns :grin: :haha:
