Steven, I use Bristlecone Shooting in Lakewood near the Federal Center. They charge $25 for members and $50 for non-members, plus the state fee of $12.50. If that's a bit far for you to drive, I've also used Foundation Firearms a few blocks off I-25 in Loveland. Dont exactly recall their price, but $35 seems to ring a bell. Easier yet, just by pre-1898 guns and have them shipped to your door.
