Join the Ben Lomond Gun Club. It's out past Kiowa a ways, then south on CR105, I think it is. Between 83 and Ramah. Really nice facility, and I've never had a problem having a whole range to myself all day. www.blgc.org I live in Parker, and it's a 1-hour drive for me.

It's a drive, and might be pricey to you, but the freedom and safety of the place is worth every penny to me. No yahoos, and no trash. 11 separate bermed ranges, two are 100 yards, others are all sizes. High-power rifle range with target lines from 100 to 600 yards. Cowboy action shooting, cowboy b/p lead only range out to 500 yards, .22 silhouettes, shotgun range, porta-johns, clubhouse (new one on the way), picnic area, RV hookups.
