No, Bob may be buying some but the majority of the rest is being purchased and hoarded by kooks that believe some of the outlandish internet rumors. No amount of truth will set them free.
Center fire ammo is now readily available in most areas while rimfire ammo shelves are swept clean each day, early in the morning by the same kind of folks that have already started to post on your thread. Lets hope they keep it up. It is very good for the economy and especially the ammo manufacturers and the middle-men in the distribution chain. They are laughing all the way to the bank.
They can keep laughing, but the tragedy is that the youth shooting and training organizations with which I am involved are running low on .22lr and cancelling events. This will be a 2-4 year break in youth who get to shoot during their formative years.
