You cannot discharge a firearm within 50 yards of a roadway(except in defense of your life, or against great bodily harm, or that of a third-party), nor can you discharge a firearm in a generally negligent way. You must make sure that you are sending your rounds down-range, into some type of berm or mound. I once had to answer a call on a gentleman that was discharging his Ruger pistol, on his property, and a few of the rounds entered a neighbor's home, with one round lodged into his refrigerator, and one into his microwave.
Do not take this as me saying that you would do this, but you must be mindful of where your rounds will go, if downrange does not have a backstop. Also, be advised that many local governments put more restriction on this measurement(though, I do not understand how, since Georgia is a "Preemption" state, but I am no lawyer). I know that in Rome, GA, you cannot discharge a firearm within either 100 feet or 150 feet(I was not a Rome City Police Officer, so I never cared about knowing). In some areas, this measurement is greater(still, the same exemptions apply, such as defensive discharge).
I am sure the information is on this site, but I could be wrong. Just check the forum that covers firearm laws(on this site), and also do a Google Search on the Original Code of Georgia, Annotated(O.C.G.A). Lexis-Nexis has the whole codebook online, accessible for free.
I have ten acres of land in Haralson County, where my girlfriend and I built a house. I have a dirt mound covering the junk pile from the build. I use that to target practice, but I also chose that area due to there being a land barrier behind that mound. I might have gone beyond what is needed, but I would rather be as safe as possible.
Good luck, be safe, and enjoy your new firearm(s). :righton: I like the new grip on the Fourth Generation of the Glock handgun. I would have gone with the Glock 22, 23, or 27(full-size, compact, and subcompact), but that is just me.

O.C.G.A. 16-11-103 will tell you what you need to know:

I meant 50 yards. Apologizes.
