The wait for first time Georgia CCW's seems to be up to 6 months now. They claim that the Georgia Bureau of Investigation has been backed up since 9/11.
I took a student to apply for hers a few weeks ago. She is now mad that she has to wait 6 month to carry legally while the criminal element is carrying illegaly RFN! I feel sorry for her, but we now have one more hard core anti-gun-law convert!
Anyway, gun ranges in the area of Marietta/Alpharetta include River Bend, a private club to the north. Nice facility, lots of rules, though. Sporting clays, skeet, trap, 600 yard high power rifle, action pistol, plinking, 2 multi purpose rifle, bullseye pistol. Initiation plus $200/year. There are a couple of indoor ranges in Mareitta, none in Alpharetta (which is in generally anti-gun Fulton County), one in Norcorss.
I would suggest that you stay out of Fulton County. Everything you have to do with the county is a big hassle. If you end up there, you will have to apply for your CCW in the Fulton County Probate Court. Even though we are a shall issue state, Fulton County will ask you why you want a permit. Even though there is no place on the form to put your answer, THEY WILL TYPE IT OVER THE SIGNATURE LINE, swear you and ask you to sign. When I asked what the deal was, the clerk said, "You can say anything you want and still get the permit. The judge just wants to know." There is no doubt in my mind that you will see your answer in court if you are ever involved in a shooting.
I had heard about this, so I had briefed my student to answer, "So that I can comply with the law." That's what she said and that's what they typed. We can live with that, but I shudder to think what some people might have said off the cuff.
