As an NRA certified Firearms Instructor these last 25 years, I have trained many MANY others. A lot of them have come back to me after their basic concealed firearms permit classes, to request other sorts of training that are of a more ... specialized nature shall we say...
No hard feelings....
My daughter was on a NRA rifle team in High School in VA, she trained with Gunny Sgt, Quantral of the Marine sniper team.
No hard feelings...
