This shortage of .22 rimfire is so universal in the US right now that a few days ago I actually saw a hand-made sign by the side of highway 17 in the Hampstead area advertising that the gun shop in the little shopping center there had .22 rimfire cartridges available. Prices for high demand cartridges like 9X19, 5.56X45 and 7.62X39 generally remain much higher than pre-Sandy Hook. Many common reloading expendables, including powders and primers, remain tough to find as well.
This remains the most profound cultural reaction to anti-second amendment efforts I have ever witnessed. Weapons that were esoteric and regarded as somewhat wicked by avid shooters in my youth are now so common as to seem a bit mundane. This is very true of standard AR-15s and AKM variants. And now the AR-10s have begun to make serious inroads into the psyche of American large game hunters. From the tidal wave of new deep concealment handgun designs that came out of cultural backlash to the Clinton gun bans to the nearly universal adoption of the AR-15 by the average shooter, It's been a long strange trip indeed.
