This unique case with a wider than normal belt was meant to provide a performance edge over the 45-70 but with a belt to ensure that it is not loaded into a vintage rifle. Now that Hornady has stopped shipping empty brass, the options are to use new Bertram brass or once-fired brass for reloading. The Bertram cases measure the original 2.09″ rather than the shorter brass now in flex-tip ammunition, which allows for a wider range of reloading options. The newly made Bertram brass is priced per 20 cases. The shipping weight is 305 g/20 cases.
