Last I bought primers was 2018. I'd love to see them drop to $50/1K as the last price I paid was $37/1K 4 years ago. I don't plan on buying any at $100/1K, but I have seen them at $75 a few times.
If they don't come down, I will consider buying factory 9mm and .223 and saving what I have left for my more expensive calibers that use the small primers, and cut my shooting of large pistol primers significantly.
But I also don't think the sky is falling. Prices will drop at some point.
Right now Vista controls 80% of the US production (Fed, CCI, Rem) with Win being 20%. Foreign primers are a pretty small slice of the pie. The cost to set up and manufacture primers is massive, and no new capacity has been added for decades. But there are 3 US companies jumping in with production at one set to begin this summer. That will help tremendously.
