Big Piney Sportsmans Club
It's a pretty nice facility, i've been down there twice now. I will likely go to some more of the events next year, but time will tell whether that'll happen or not.
Since I made this post I have found some private land with several range opportunities from 100 yard, 600 yard, and move to another location on the property and according to google maps I can get upwards of 1300 yards. All with solid backstops and a lot of unoccupied land in case of a ricochet.
