I have no idea of how it will affect the retailers, but what I hear from reliable sources is that the factories are running 18 months behind and not accepting orders from distributors at this time. Looks like it will take some time before supply gets back to normal! (sigh)
From an ammo producer from one of the local boards I frequent;
I talked to one of the OEM sales rep I deal with from a large ammo mfg that has been around for a long time. We got to talking the other day. We got on the subject of primers, he tells me that they make in one factory 4 million primers in one shift. They work 3 shifts, 7 days a week. He also said they have not had a positive primer inventory since '06. Now of course not all of the primers they make go on the commercial market for reloaders, but this gives you an idea of the volume of what one manufacturer makes. With this in mind it makes you think diferently about the shortage of components.
