I've been on a city planning commission, and I belong to a Club with a shooting range--and to top it off, the range(s) and property have some unique problems--such as a housing development downrange from them.
I suspect where you are trying to buy would be more gun-friendly than where we are. But, based on my experiences / knowledge of the situations up here, I would plan on 1) buying the land conditionally and 2) preparing for a somewhat-tedious process for the Zoning and Land Use issues. Be prepared to be able to show some (land) development proposals (architectural renderings) that will answer any questions from access and parking needs on through to range design and the obvious safety ones. I don't think there is any way around those city / state / county / gov't needs if you plan on allowing people other than your family shooting on the land.
What you are going to be striving for would probably be a zoning change for a range, and not necessarily for commercial use. Another angle on it would be getting a Conditional Use Permit--and hopefully, one that does not need to be renewed annually. Unless you plan on having this range strictly for personal use--and the existing laws and rules allow shooting on your own land--don't even think of trying to slide by the zoning change and notification needs.
The NRA contact above may well be able to help you on that, or at least redirect you to the NRA legal types who can point you in the right direction. Independent of them, I would also contact any local shooting types, including LEO, to get the name of a local lawyer who may well be a shooter and who does real estate stuff.
