Yea. I remember that 22 sold out back then too. There was a constant stream of threads on all the boards about Wal-Mart being out of 22 ammo. People were camping there to buy it as soon as the truck came in. Then they'd take it to the gun show and double or triple their money. Same thing at my LGS really. Eventually retailers started to ration it to give more people a chance. Eventually the supply caught up with the demand and things cooled off.
It may have happened quicker this time because a lot of people remember the last time.
For God so loved the world, that He gave His only begotten Son, that whoever believes in Him should not perish, but have everlasting life.
John 3:16 (NKJV)
