So, apparently, ammo.com is experiencing a surge in sales in the last couple of weeks:

North Carolina and Georgia lead the pack with 179% and 169% percent increases, but other states notable jumps include Pennsylvania (140%), Texas (128%), Florida (76%), Illinois (67%), New York (48%) and Ohio (40%). I suspect the absolute increases were strong in many other states, but they probably start from a higher base in terms of typical ammunition sales.
Speaking of starting from a low base, that’s maybe the only explanation I can think of why among calibers 40 S&W saw the biggest increase at a whopping 410%.
While the particulars here are from ammo.com’s numbers, I think we can assume this represents a fairly broad trend. And obviously this is Covid-19 driven phenomenon.
And Gold is up too. I have heard it said that ammo sales and gold often move together. Makes sense: both are types of insurance.
