For primers, I think we're at the peak and coming down. 6 months ago, you would never see 2 major online dealers have primers in the same week. Now, this past week, I have seen Powder Valley, Brownells, and Midway all have a few different primers. I think the peak was a month or so ago. 6 month's ago, Gunbroker was about $150 - $175, but you could get lucky and get them for $125 final price. Currently, prices on Gunbroker are higher, like $175 - $200, as people have given up waiting and will pay those prices. But, now that some primers are trickling in here and there, those Gunbroker and gun show prices will start to drop.
Also, for people like me, that added some new calibers to their collection and want to reload instead of pay ridiculous prices for ammo, we will pay a little high primer price. I have recent bought 2 bricks for $130 and $90 each to allow me to shoot new guns with ammo that is much better than factory and way cheaper. Now, that I have stocked up a bit, people like me will leave the $90 - $108 bricks to the next people in line. Once they get stocked up a bit...prices may lower.
But, I bet there are a lot of people lined up.
