Look, I honestly don't care how much ammunition anyone wants to have, it is a personal choice.
Before prices went insane I used to buy a brick or 2 of .22 every pay check, occasionally other calibers as needed. I never had thousands of round of ammo on hand but I had what I felt was adequate for my needs. Even today I buy a few boxes when I have some extra money, but I am never the guy waiting at the door of the (insert store name here) for them to stock the shelves so I can empty them. I buy most often at 2 locally owned gun stores, and a couple of hardware stores that sell guns. Their prices are great, the availability has been good, other than .22lr, AND they are a part of the local community so the money stays here.
Again, I am not judging anyone or what they do, just explaining what I do. Yes, I have some ammo on hand. How much? None of your business.
