I never bought much .22 LR ammo at Walmart, as several gun shops and the net beat their prices. In 2010 I noticed the supply of .22 starting to dry-up and began purchasing several bricks of my favorite rounds-Federal 510 and CCI Standard whenever I found it on sale. So glad I did, as any .22 ammo is unobtainable right now in W. PA.

The other caliber you can't get- .30-30 Win. Guys are trading-in many .30-30 rifles for .270's, 7MM's and other calibers because there is no ammo for the venerable lever guns.
