Longmont just finished there police range which will be open to the public which is Another option you somewhat have to join as well and buy passes but it's a option. Check for more information on Longmont police website! Typing this with my phone!

You could join trigger time as said before, but again it's pricey, but you do get a nice faculty to shoot in!

Other option is shooting at boulder rifle gun club during public range days first weekend of every month in the summer and ever weekkend in the fall for sighting in. It's ten bucks if I recall. Would also suggest getting on the wait list cause it doesn't hurt and costs nothing!

Another option Would be joining colorado rifle club out in Byers it's about hour and half away but you have everything including a 1000 yard range. The distance is a downer but it's worth it for me being there is not many ranges with longrange in are area. Cost is only 65 a year plus work bond which isent bad for everything you get!
