Inflation and stagflation were major factors in the late’70’s/early’80’s shortages. There were a whole lot fewer handloaders back then and more people kept years/decades of supplies on-hand for the atomic holocaust. Underground bunkers, dried food stores, water tanks and diesel hoarders… everyone was a “prep’r” back then. That made it less of a panic. And, the news had more important things to talk about back then than ammunition prices, too. Gas lines, race riots, environmental disasters, the “scourge of the Vietnam veteran”… drug wars were not a thing yet, as far as Walter Cronkite was concerned. That was later. Anyway, yes there have been other reloading supplies shortages where inflation was a factor. They were just a little before The Internet became people’s sole source of information.
