Okay so some how or another you have missed the end of the world(coma, drug dazed whatever you pick it)
Using your criteria, I would assume the internet would be down. My loading manuals wouldn't show rifle loads using Unique, or handgun loads using Varget. So I would fire up my computer with Quickload on it, and determine some loads that used the components I had on hand. So if I had to use Unique in a rifle, at least I could see a starting load to work from.
But as others mentioned, reloading would be pretty far down my "To Do" list.
