Sparky,
There is an actual map that sets the boundaries for permissible outdoor shooting in Clark County. I believe that Master Shooter's Supply on West Sahara gives them away free of charge. Or, perhaps if someone on the board has one they can scan it and post it in the thread.

Just a suggestion when shooting in the desert in Clark County: If you have handguns with you make sure they are all registered and you actually HAVE the Blue Card(s) in your possession. A friend of mine had a gun confiscated by NHP a few years ago while he was out shooting in Sloan because he couldn't find his Blue Card. Although he honestly lost the card, it didn't carry any weight with the Trooper and he still impounded the gun anyway.
It took about three weeks and almost an act of Congress to get the gun back, because Metro will not issue a duplicate Blue Card without physically seeing the handgun, and NHP will not release the gun without a Blue Card. According to my friend Metro was great and they tried everything they could to be of assistance. It was NHP that gave him the hard time.
Eventually, a Sergeant or a Lieutenant at Metro sent a letter to NHP and that took care of it and he finally got the gun back. I would hate to have a brand new, high quality, high dollar gun taken away just for the Blue Card issue.
Hope this helps.
Be Safe.
Joe
