I bought more ammo for both my handguns when the pandemic lockdown started-there was plenty of ammo for both .38 and .357 then, but when the anti-lockdown protests started in cities, I heard from a neighbor who went to the same place to stock up that they were low on all ammo but rifle-made sense to me, since a rifle probably wouldn’t be the 1st choice of self-defense weapon for most of us...
We had pallets of AR-15s and 5.56mm ammo for them, all gone.
Rifles with 30 round magazines make sense for defense against mobs.
