Well you wouldnt because its cyclical. In 2012-13 primer manuf did go 24-7 but held off building new facilities. This is a bit diff. With covid, they really cant run 24-7. it would require time between shifts to completely clean & sterilize, every day, every shift. Otherwise they set themselves up for lawsuits. No this is diff. All pistol primers are going into ammo.
I doubt hoarders are causing this. There are 25M new handgun owners, probably as any new rifle owners. If everyone just got 100rds of ammo with their new toy, that is 2.5B rds. Then add in al the regular buyers that are adding to their supplies. Then add all the govt contracts for ammo. Then throw in the icing, which is the election. This wont go away until well after Jan & that is if Trump wins. If Biden wins, I dont see any let up, maybe next year about this time we see primers, maybe.
