Brandon at Rocky Mountain Guns and Ammo is looking to open a range in Parker eventually. Sounds pretty cool (indoor 100 yard). I'm not sure on the timeline.
I'm near Parker and head to Cherry Creek Family Sports Center for upto 100 yard rifle and 7 yard pistol. They have a shotgun (trap) setup as well. I've never tried there trap.
Another consideration is the Ben Lomond Gun Club (BLGC) just north or Ramah. You need to be a member though. The range is about an hour from Parker but worth the drive. They have a high power rifle range to 600 yards and many, many, other ranges.
Best of luck.
