The Mrs and I came across this place a couple months back:
Located about two miles north of Rainbow Creek Riding Area on Hwy. 67 North of Woodland Park in the Hayden burn area. It's not great, but it's free, has about 12 shooting areas 300+ yards. separated from one another, a couple of them slow for 100-200 shots. BYO everything, no facilities, and most people leave their garbage behind, but it exists.
