Jake at RMR got "burnt" during early days of his business when his wholesale order got cut and outpriced by manufacturer of bullets he was retailing during a component shortage (Won't mention the name of bullet manufacturer).
That partly pushed him to manufacture his own jacketed bullets to "match grade" standards and during the "Great Component Shortage" of 2013, he decided to more than double his production capacity so he could produce bullets without being "out of stock".
Well, after ELEY and other ammunition manufacturers contracted with RMR, I think he like ended up with quadrupled production capacity so during Covid component shortage, he was mostly "in stock" with some delays.
