Defensive Concepts is GTG, they just need to have more classes in this part of the state
You really just have to keep your ear to the ground in this area. I took a Kyle Defoor class last year in Bostic and then Pat Mcnamara hosted a rifle class a month latter at the same range.
I know of a few long range rifle classes and matches, but they are more in the eastern part of the state.
There are some good 3 gun matches that myself and some other ARFcom members shoot at every month. COG 3 Gun is the best one IMO, but its about a 1 1/2 drive from Hendersonville. Let me know if you are interested and I will give you the details and you can shoot with us.
If you are into IDPA there is a great match in Spartanburg SC that is worth the drive, There is also a IPSC match that should be very close to you.
I am always up for some quality training if you find something I have missed shoot me a PM and keep me in the loop.
