Some of the problems causing the problem.
1. Remington is no longer producing ammo so that takes millions of rounds off the shelves.
2. There are a whole lot more new gun owners now than just a few years ago so more ammo was bought by them.
3. Because people are scared, they/us, bought up more ammo/components than most will ever use in a life time.
4. From what I have seen the factories are running 24/7 and have increased output. But here is the problem. COVID 19 In the factory if one person test positive they have to quarantine EVERYBODY this person has come in contact with for 14 days. That slows or shuts down production. You can't just go out on the street and bring in Joe and have him fill in for any of these trained workers.
5. Then there is the problem of the ammo/component companies getting the products they need due to the same problems COVID 19 caused them with having to slow or shut down work. It is the snow ball effect.
6. Even when things start to settle down it will take a long time because as soon as something shows up on the shelf because people are scared they will purchase IT ALL in stead of just some of it and leave the next guy without any.
I don't see things returning to the "old days" for a loooooog time if ever.
