Well there's Dragonman's out east of town (I don't like shooting there and it's not free but it is open to the public).

There are a few members only places in the area. I'm a member at Frontier which has a range out by Falcon and one down by Fountain. They're cheap ($75/yr with no per-day fees) but there's a waiting list to become a member and membership doesn't open up until February but overall its a nice club.

Up north of town is Ben Lomond Gun club. Don't know anything about them other than what's on their web site.

Pikes Peak Gun Club is apparently a good place for trap and clays (although I believe they have other ranges too) but they're a member's only range.

Whispering Pines is the only indoor range in the area (but it's a member's only place too)

The free range up Rampart Range Road has been closed for a while now (and even if the range hadn't been shut down it would be closed right now because of the Waldo Canyon Fire).

The county is planning on opening a public range as a joint venture with Fort Carson (it's past the end of October and I don't think it's open yet but I don't know).

There really is a dearth of places to shoot around The Springs that are open to the public.
