Yeah, the post-Obama ammo scare in '08-09.... good thing was everything was out of stock, except 22LR.Yup, if you were around to see the Dec 2012 "Panic" then you know what normal was between 2017 ish - Jan 2020. That was the time to buy, if you weren't good already pre - Dec 2012..
They would limit you to 4 items per day (to give everyone a FAIR chance, lol). I would by 4 bulk 22LR packs every day or so - 550s were like $12.99-13.99 or so, the 333 and 500s were less, in the $8.99-10.99 range. I had a 40-gallon Rubbermaid bucket stacked to the brim with those. Man it was a PITA to move, so damn heavy. 2-ish cents a round, give or take.
Every other kind of ammo was gone for months except 22, which would sell out occasionally but then come back in stock again.
