It apparently depends upon the area, but I don't recall seeing 30-06 or .243 out of stock very often even during the peak insanity at most stores that I visited. It was surprising to me, though, because those two are such popular calibers. Those were very lonely though, as probably 80% of the other shelves were bare most of the time. I never paid attention to some of the other calibers that you listed so I can say about those. .22 rimfire of all types is STILL a rarity!
