These guys die eventually. I went to the estate sale of one of the retired ammo hoarders buying all the 22lr ammo from Walmart back around 2016. They guy had at least 80 thousand rounds of 22lr ammo.
I didn't buy any as I just off loaded all my 6 to 22 year old 22lr ammo during the height of the plandemic.
Supposedly one of the reasons primers got expensive is some of the chemicals got expensive and hard to find, back ordered ect and everyone in the US that makes and sells primers more or less uses the same chemistry primer. Lead free primers use different chemicals, the hardest thing to do with lead free is grind up aluminum into powder so fine its on the verge of spontaneous combustion on contact with air. Too fine it catches on fire on contact with air, too course and the primers don't work and charcoal can't be used as a stabilizer/buffer like with normal pyrotechnics powdered aluminum.
But Russia seems to have figured it out 20+ years ago.
