I agree, reloading is a good plan, if the only ammo available is 600 miles away, brass is going to be hard to come up with.
True, if you leave it to the last minute. You can obtain enough supplies (brass, bullets, primers, powder) within a week via mail order to make enough ammo (any SAAMI spec caliber) for years of hunting. Leaving ammo purchase/manufacture until the last minute is not usually a good idea, especially since each load should be zeroed before you use it on an animal.
