Within the past few weeks I've visited Walmarts in Crestview, FL; Chantilly & Charlottesville, VA with the same result: bare ammo shelves. The only calibers they seem to have in stock are 20ga, .30-06 and .243.
I've come to realize that WM not longer stocks their shelves. They now only plink them, and if your not there to catch the deflections your SOL!
