I went to J & G Sales Limited in Prescott, Arizona (the same as the one that has a link online) to purchase a case of .223 ammo. For the purchase of the ammo they have a store policy that you fill out and sign a form, in triplicate, giving your physical home address, certifying your age and the number or rounds purchased. I assume this is for any 'volume' purchases - whatever constitutes a volume. And, the form was nothing like the form filled out to buy a firearm. When asked about the reason(s) for the form their only response was, "It's just our policy". Prior to the purchase of the ammo I was forced to prove my physical address. If your driver's license has a different address than your actual physical address, and you have no sufficient proof of your physical address, you have to go to DMV to get a copy of your driving record to verify your physical address. Where I live all of our records have a PO box for mailing since there is no delivery of mail to residences. I know of no federal or state law requiring one to show proof of physical address (other than what you would voluntarily put on the BATF form when you buy a gun). I am certain the folks at J & G are pampering our boys at BATF by giving them your name and address for volume purchases of ammo. I have made large ammo purchases at other gun stores throughout Arizona and have never found another to require the filling out and signing of the physical address form. Needless to say I have made my last trip to J & G Guns.
