I'd swear that some employee in my two local Wal-Marts is in cahoots with someone who buys up all the .223/5.56 before it even hits the shelves. I gotta schmooze the gal that works the sporting goods counter a little better, I guess ... (yeah, I confess, I hit up Wally World a couple times a week -- it's on the way to work -- and I've been in the habit of regular ammo and bait runs while also picking up cheap DVDs/Blu-Rays and Sam Adams when I'm there).
We got plenty o' .17 HMR and .410 available, but that's been about it since the silliness started. Oh, and yeah -- NOW there's plenty of .380 around, after I traded off the PPK and 232 ...
