Just keep one tiny little detail in mind when looking for Outdoor range space. Well 2 things first: A) My information is at least 20 years old, B) I do not know a thing about any part of Tn with the possible exception of Nashville (no I did not go see Graceland, Elvis was still alive then). So I do not know if this will actually effect even the idea of having an outdoor range, Especially a range capable of rifle shooting
The US Coast Guard will NOT allow any shooting range to be built within I think it was at least a MILE of any navigable water way that comes under their jurisdiction, which I take to mean Rivers, Canals, Bayous, Lakes large enough to rate a Coast Guard station however small, etc. If the water anywhere with in a mile of your range is under Coast Guard Jurisdiction, they will veto the entire thing. Double check on that/this, since as I said my information is OLD. I know this because back when I was with the Sheriff's Office back home the qualification/practice range that was not just used by my department but 3 other Departments as well was shut down by order of the Coast Guard after a Canal or Bayou got dredged or built (I forget which) that was deep enough to have crew boats, and other commercial and sport fishing vessels use it. And the Range had been there for over 25 years BEFORE the waterway was built or deepened or what ever. And the range was actually Barely short of the 1 mile limit, Didn't matter one bit, The range was closed and it was a year before a new site could be found and built up.
