It's not close to Evergreen, but Ben Lomond Gun Club has very nice facilities, with a high-power rifle range out to 600 yards. Kind of a drive, but no waiting list. www.blgc.org There's also a nice DOW public range on US40 between Hot Sulphur Springs and Kremmling, also a long drive but scenic. Don't know the range distances though, farther than I'd want to walk, for sure.
