Back before Obama was elected in 2008 and I shot thousands of rounds of pistol ammo every year I stocked up during group buys that were run from my club. Thankfully I have enough components to last me probably 15 years since I only go to the range once a month anymore.
Once things settle down just start picking up a box or two every payday or components for loading your own every payday.
A little adds up pretty quickly. I did that with .22lr before any of the rushes. Probably won't run out of that any time soon either.
