Our only indoor range around here (Greenville, SC) has the same $5 fee if you bring in your own ammo, member or not. I agree that with a membership you should get a few perks. I don't reload yet, but the policy at the range is you cannot collect brass and I am understanding that means your own as well. I understand not taking the brass from the range ammo, but if I brought it I am taking it back with me.
