Look on-line. There is still .22 LR available, but you must look for it.
Sure there are, care to post some links? There has been no 22LR on the shelves here for weeks, when there was it didn't really get to the shelves as people were lined up to buy it.
223, 30 cal, 30-30, or 30-06 dream on.
Some 223 can be had for #1.00 a pop so load up and go practice a few hundred rounds this weekend, enjoy.
