Hunting rounds are not as rare yet, but as demand for the big three (9mm, 223, & 308), goes up, production focus will shift away from hunting to handgun/black rifle rounds. 22LR is not much of a money maker for the ammo companies and is normally the first to limit or cease production in favor of others.
It is perhaps a 2 weeks away from really being noticed. 9mm is selling for up to $2 per round and 223 is selling for around $1.00-$1.50. There was a Canadian company who purchased most of the distributor inventory in Canada and exported it back to the USA when they relized that there was a premium to be made on the market down there.
Prices will probally not rise here, more likely product will just disapear.
Somone I know well from the USA asked me where he could by 223 ammo. I told him that, I had no idea and asked him why he wanted more (he had 8 cases). He said he was buying it for the purpose of using it as currency incases things head south. If even 5% of the nation starts to think that way, you are looking at months or years of shortages.
Thanks for the heads up
