They open up the range on weekends a lot of times for "Rec fire" -Recreational shooting. The first order of business is for everyone to put up their targets and then they start at 100 yards and as the day goes along they move back usually to 600, then 800, 900, and 1000. You pretty much have to be there first thing in the morning in order to get your 100 yard zero.
I will let you know the next time they do. It might be that they will open it up this weekend.
