Not in the past 34 years or so. But back in my youth, if you ran out you just went to the sporting goods store, showed them your driver's license, filled out and signed a ledger book, and got another box.
So yes, I may have run out back then. Being armed at all times didn't seem to be that important to everyone like it is now. America must have been totally crime free in the 70s. Wasn't legal to carry anyway, unless you were a cop, and even they could only carry what was authorized by the department. Everything else was just hunting and target practice. No big deal to be out of ammo, just pick some up before your next hunting or range trip.
