You can get lucky.
There is a C-A-L ranch store here in Pleasant Grove, Utah, and while I was standing looking at the bare shelves of ammo yesterday a salesman wheeled in a cart that had a case of .38 special bullets — $16.50 per box of 50 cartridges ( CCI Blazer Brass FMJ ) The catch — 2 boxes per customer per day. Between my daughter, my wife, myself and 2 days, I got ten of them. The salesman said that such shipments usually last on the shelves 3 hours when word gets out.
