In the worst of the shortages a few years ago, very many people switched to .22's - which in some areas were itself a bit scarce. I'm sure many of us recall the stories of people showing up at WalMart at 0700 and staking out the Sporting Goods section for their daily limit of 2-3 boxes.
It’s definitely more of a buyer’s market as far as reloading. I had taken some time off from reloading, as i had assembled and stockpiled all my hunting calibers. But I saw primers at a decent price the other day, I got pretty excited!
