Call Tom at
http://www.shootingsafaris.com I took my Dad out with Tom for his "Police Patrol" program a couple weeks ago for his 60th B-day and it was great.
Shot 12+ weapons including the 44 Magnum (and a handgun bigger than that 460?) sniper rifles from 200 yards.
If you just want to shoot clay, I'd still contact Tom, he works at the Clark County range that is referenced in the first responders post.
Have fun!
