Jason Vanderbrink is the president of the division that makes Federal, CCI, and Remington ammunition. He releases a video on Friday regarding the ammunition shortage. He tries to dispel some of the misinformation, rumors, and out-right lies.
I think he has got it right – the increase in new shooters has increased the demand for ammunition. When you add that, COVID-19, and the need to train new employees, it does account for a good deal of the shortage.
