I am not buying ammo at all right now. The prices are way too high. I did buy an AR-10, but at pre-panic prices; and I paid $5 more per brick for some .22LR, but it was there, and so was I....
I am proud to be a prepper, and I had purchased ammo when prices were "normal" because I track events as part of my daily situational awareness routine. When Iraq invaded Kuwait, I heard there would be a shortage of .223 ammo, so I stocked up. When the elections looked like the Republicans would lose the White House and a President who said he favored gun control was running and gaining in popularity, I bought more black rifles and more ammo. If you were tracking events, you could see this coming from a thousand miles away. I have sold some guns, and some ammo, to people I trust, who needed help, and who are also neighbors and are like-minded people, and who are now great friends and future allies.... My kind of politicking....
The ammo shortage is being created the same way all shortages occur - by speculators buying up available supplies to resell to panicky buyers dumb enough to pay inflated prices for goods.
The shortage will end when the newbies, grasshoppers, sheeple, and slumberers have either found what they think they need, or they run out of money or credit, whichever comes first....
And then the ants and preppers will quietly go about their tasks, unnoticed by the stultified, and filling up their larders for the next mass-media-induced panic buying frenzy, or emergencies.
