I know this is an older thread, but I visited Colorado Clays last weekend after seeing their booth at the Outdoor Expo and speaking with the owners for a few minutes. Their 100 yd rifle range is completed and it is pretty nice. They offer a covered shooting area with a space heater above each bay for those cold days and it is semi-enclosed. They have a video target viewing system. It's $20 per hour and you can take as many rifles as you want as well as switch over to the 25 yd pistol range with auto retrieval system. They told me that as long as there is no line, you can stay longer. I know they weren't clock watching last weekend because I was setting up a scope and stayed for over 90 minutes and used both the pistol and rifle areas. First target is free and then they charge $1 per additional target, or you can bring your own and they will put it up for you. The RO will meet you outside and check your ammo (no steel ammo allowed), and go over the rules and they we're actually quite friendly during my first visit. While I was there, I think the most rifle bays being used at any one time was four or five, so it wasn't too busy. The pistol range was a tad busier, probably had 6-8 bays being used at its peak.

Also, they will let you keep your brass, but a lot of it does tend to go beyond the red line, so I'm going to get a brass catcher for my next trip. They sell surplus brass for $5 per 105 of .223 and $10 per 105 of .308 and you can go through the bins and pick out what you want if you want to take the time. They had other calibers, but I didn't check the pricing.

All in all, it was a good experience and I will be going back for sure!
