Open range, as it is called, provides a lot of shooting opportunities out west. It is usually nationally owned land, like a national forest, but is open for recreational use, and target shooting qualifies as legitimate recreational use. You would not be hunting (requires a season and lincensing, etc), and don't shoot and destroy anything, get about 50 feet off the road, shooting away from any road or "civilization", and you should be good to go. If in doubt about your area in question, consult a local police officer or agency, and they might even give you tips as to where to go for the best opportunities for an open range. Some BLM land is given to control by individuals, and they can restrict access for hunting and such, so you need to know where the access paths are so that you are not trespassing. Do not ASSUME all open areas are gun free zones. I go to Colorado, step out into the national forest, and "plink" to my hearts content (always a safe, uninhabited area), and no one ever bats an eye.
