Hey Corn, I feel you pain. The cost of weapons is exorbitant. I went ahead and picked up a Curio and Relics Federal Firearms License and this has opend up many doors. You get your weapons sent straight to your door. I get discounts from various vendors because I am considered a collector/dealer. You will be amazed at some of the weapons that will be available to you.
Another note...I was stationed in Vicksburg for many years (412 ENCOM). I loved Vicksburg.
