American Arms and Supply seems to have the most consistent stock of ammunition. They've had .38, 5.56/.223, 9mm, .22, .40 in stock at various points in the past couple weeks. They usually post on their facebook page when they get ammo in. American Arms and Supply: 15531 Manchester Road Ballwin, Missouri 63011 (636) 527-1839 http://www.facebook.com/americanarmsandsupply Also, last time I was there On Target had a decent selection too. On Targert: 590 Vance Road Valley Park, Missouri 63088 (636) 861-1055 The Wal-Mart in Warrenton, Missouri had two boxes of 9mm there a week ago, but that seems more like a fluke.
