OK, I finally gave in... Most stores I've been too don't have .22 LRs, .22 magnums are a pipe dream.
I found one store that had acquired some .22 magnums off of another customer and I was lucky enough to get a couple of hundred rounds. I probably have driven at least a 150 miles to different stores in search of the illusive long rifle only to find a couple that had them and they had a 50 round limit.
I just bought a 500 round brick off of Gun Broker, cost plus shipping was $85.00. Although, the price bites - at $3.35 per gallon of gas, it's still probably cheaper than driving around and only finding a few rounds here and there.
I will remember these days well when I vote in 2014.
