Noliver....there is a descent 100 yard range in Richmond Hill out 144.
I go there a good bit. Ga recently changed a few regs and now require aGORP pass to be able to shoot at most or all state shooting ranges. I have the Sportsman pass which includes hunting /fishing and it clears you of having the GORP to shoot.
Im including the page of ranges...scroll to bottom...
