Would like to find a good gunshop or two in nashville or the surronding area.
I would be interested in about any place that has several rifles but I am more interested in a place that carries either a few 375 H&H and up rifles or double rifles etc.

I have no idea if they have any today, but if any shop in Nashville would have the odd double gun on the shelf it would be Game Fair Ltd.

Guns and Leather about 1/2 hour north on Hwy 41 near Greenbrier has a good selection of the more standard gun shop fare.

GunCat has this exactly right.

Game Fair is owned by a man that I have known for many years. Although fly fishing is their specialty, always many firearms...all used, in my experience. Bring your wallet. Nice folks, too.

Guns and leather is an excellent, more traditional gun shop. Fine inventory, and they can and will get you what they do not have in stock. Good gunsmith available.

Given what you are looking for, try Game Fair first. Their Web site is quite good. Just google them.
