Strategic Edge does more than precision rifle classes. BTW, I
highly recommend the SE PS I course. I took it last year and Tony (the owner) is an excellent teacher.
There is Marshman Training just south of the border in Elkmont AL:
https://www.mtcrange.com/about-us Know nothing of them but their website.
There is a 1000 yard range NE of Pelham TN. I had to cancel from a 2 day PR course last year unfortunately. Elk River Training,
don't have the link handy. https://www.elkrivertrainingcenter.com/contact-us/There is a range east of Ethridge, TN (Lawrence county), don't recall the name, but they may have training courses. They shoot IPSC/Action Pistol type matches.
There is Top Guns also near Ethridge, TN.
https://www.topgun-arms.com/ These guys probably know about the range discussed above. They are not the same.
There is a big rifle range north of Dunlap, don't recall the name, but someone here will remember it. Don't know if they offer training, but the range is highly spoken of here. Dead Zero, something like that.
