The "ammunition shortage" could also be just like the "toilet paper shortage". People heard there would be a shortage or thought that a shortage would occur, and so went out and bought up as much as they could, thus creating an actual shortage. Then when an actual shortage becomes evident, people started panic buying whatever they could get their hands on. The same thing could happen with firearms.
So this might mainly reflect panic buying by existing users rather than mainly people who didn't have guns going out and buying them.
Supplies for hand loading would probably be less affected by this sort of psychology, as people who hand load typically buy in bulk and so already keep a good sized stockpile and are therefore less subject to panic buying impulses. I suspect, going from what anecdotal evidence that I've seen, that people who hand load are also in an older demographic and less inclined to spend their time glued to Facebook and Twitter on their iPhones and so less exposed to people posting about shortages of either ammunition or toilet paper.
Well TBH honest mate I really don't know about elsewhere in the country, I do know that folks around here aren't stocking up (panic buying). As I said to Jonesy there, I phoned the local gun shop earlier today and they are okay for ammunition.
That will probably change though when they try placing their next order. Personally I'm not concerned as I have enough ammunition made to last a good long while.
