I visited a shop called The Outpost off I-24 just south of Murfreesboro a couple of weeks ago, and it's a pretty nice place. Lots of gun selection and much ammo and reloading supplies. It also has the largest selection of .50 Barrett rifles you'll likely find in one place. I think that's because it's associated with Barrett Rifles whose manufacturing facility is in Murfreesboro. The shop is about 30 miles south of Nashville and well worth the trip if you can make it. I picked up an 8 pound keg of TiteGroup for $135, which is an OK price if you can find it. Titegroup is in short supply these days if you check the Internet.
