Very good article Jim! I did know Vista Outdoors owns Alliant powder, Remington (ammo), CCI and Federal. I didn't know about the Russian primers available in mass in the market in 2008. Maybe explains some of the current primer shortage? Thanks!
The current shortage is completely different. You also have several factors.
Primers are over run components from manufacturers. With the demand of ammo, they had no overage of primes.
People could not get the none production ammo, so they start reloading. Components fly off the shelves, that creates even less supply.
The Ukraine was is taxing ammunition supplies
The government not allowing foreign ammo sales from certain countries is also hurting supply (by design).
It is not a simple issue, it is not something that will be fixed soon either IMHO.
