Word from our supplies wholesaler is that many manufacturers, such as Winchester, are holding back primers for use in their own ammunition lines. With ammunition prices skyrocketing it makes sense that they would try to capitalize on the profits. We often want to attribute noble sentiments to gun related manufacturers but they are just businesses like any other, and they are in the business to make money. I have seen loaded ammunition prices passing the $1 per round for 9mm, 40 SW, 45 SCP, etc. and rifle ammunition like 223 well over $1 per round. So I am not surprised to see primer prices rising. I have seen an increase at the wholesaler level on primers and powder. While it is not as bad as what we are seeing in the private market, it is still a bothersome trend.
We have gotten word that the companies still manufacturing and selling primers are backed up to almost 6 months out. Of course, that is not taking into account a possible Biden win.
It really is the simple law of supply and demand. Those who have the supply can demand the money.
