Half the household in the USA had a 22LR rifle and ~25 rounds of ammo in a 50 round box, and consumed 2 shots a year, when obuma took office.
For $40 and 0.2 sq ft of closet storage space one could get a brick of 500 rounds of 22lr ammo.
Who wouldn't want to do that?
The trouble was 22lr manufacturing requires very expensive tooling. The manufacturers would run 3 shifts, but would not buy new tooling.
That hoarding and maxed out production fed on itself and caused years of shortages.
