I read an article sometime back (about February or so) that US ammo manufacturers had ramped production to around 1 billion rounds per week. Even if the .gov were buying 5 billion rounds per year, that would be less than 10% of the annual supply. A local gun shop in my very rural area managed to procure 2.3 million rounds of .22 LR around that same time. Even with one brick per person limits it was gone in around 6 weeks. One guy drove from Alabama to buy one brick. The government has nothing to do with it. The buying power of American consumers is unfathomable.
