From The Reload:

As store shelves lie barren and prices for the most popular ammunition hover at two, three, or even five times their pre-pandemic levels, manufacturers said they are still scrambling to bring enough product to market. They said they are still working through several years’ worth of orders that have already been placed.

“On certain products, we are certainly seeing backlogs that stretch out two years and beyond,” Brett Flaugher, president of Winchester Ammunition, told The Reload. “For those who shoot 9mm and 5.56 ammunition, which are both in high demand, it’s very uncertain how long it will be before people will consistently have ammunition readily available.”
