That place teaches you just about nothing... If you arnt as familiar with firearms as some of us, I would highly recommend a longer, in person class.
I only took the concealed-carry.net class because of time constraints and because I know more about firearms than the average person. I never recommend it to friends.
In NOVA, you have both Blue Ridge Arsenal and the NRA range. Both, im sure, will accommodate a private lesson with lead free rounds...
