Re: any free ranges around Nashville?
Unfortunately there aren't a lot of good options for rifle fire. There is a public range on Hobson pike that does allow rifle fire: TN STONE RIVER RANGE,
2618 HOBSON PIKE, ANTIOCH, TN 37013.
PHONE: (615) 361-1121
If you're wanting to shoot handguns, there is a indoor handgun only range in the northwestern end of the county call the Academy of Self Protection. I've used their range a few times and had good experiences. There is also an indoor range about 20-30 mins outside Nashville in Greenbrier called Guns and Leather. They also have a pistol only range. It's a nice range that I've used pretty frequently. Let me know if I can be of further help. I live in Nashville.
