Also, there is no way prepare for constant shortages. How much is enough?
Well, while we cannot be prepared for every shortages, most of the shortages can be smoothed over with a little planning, both in the best of times and the worst of times.
You keep an inventory of ammunition on hand to cover some period of time. Currently, I plan for a years worth of shooting. During the year of shooting, I keep watch of what is on the market and the cost.
I replace some or all of what I need when I find a deal. I might even pay a small premium for a small amount to replace a small amount of inventory to extend the date i run out. But, I have a year to be picky on price if i want.
If I was actively competing, you bet i would have a good inventory on hand and would be looking to replace what was shot as frequently as I could.
Even in the best of times where large ammunition purchases are made, spot shortages can happen just because. It does not take a tragedy to create a shortage in those instances.
If you are shooting "hand-to-mouth" during these times, expect to be disappointed when waiting in line at Wally World, expect to pay high prices from scalpers since you missed the shipments at Wally World, and expect to be short of ammunition.
Finally, some folks who feel the ammunition companies are to blame for the shortages and high prices may want to stock up on aluminum foil.
