Experiments in Making 11mm/.43 Mauser Brass

The Mauser 1871 was the first rifle designed by the Mauser brothers to be adopted by the Imperial German Army. It fires a large bore black powder cartridge, 11.15x60mmR, commonly known today as 11mm Mauser or 43 Mauser. To reload for these old rifles, there are die sets available as well as bullet molds. However there are only 1-2 makers of brass cases and they are either out of stock or very expensive when in stock. As an alternative, I'm experimenting to convert other cases to work, both 300 Winchester Magnum and .45-70. In this video I discuss the methods of conversion and decide which is the better option.
