The CRCI.org site is the Colorado Rifle Club. It is a private membership shooting range and is one of the best in the state of Colorado. I have been a member for the last 7 years. Pistol, Small Bore, Schuetzen, long range 1000 and the 500 meter Silhouette range are just a few of the shooting ranges.
There are sometimes shooting Tournaments going on that can also cause confilcts with personel shooting time.
I have heard of the shooting range, Ben Lomond Gun Club, but know nothing about the facility.
If you are a NRA member Raton NM has the Whittington Center and it has very good shooting facilities.
Find some good public land and set up a target pad and laser your own range works pretty good also.
Also the suggestion for the dragonman is probably one of your closer bets.

Also check the colorado department of wildlife website some where on the site they list some private and public shootings ranges
Oh that reminds me there is the golden gun club near Watkins Colorado, also they are a private club but are open to the public for a fee during hunting seasons for site in Golden Gun Club - Denver's Premier Shooting Facility
