Do you intend to shoot it? It is also called the 11x58R Werndl, BTW, but you prolly knew that already. There is a movie on Youtube about making the ammunition. All you need is a supply of the .348 Winchester cases and a lot of patience. The 210gr bullets might be problem to locate, too.

Note that without the internal magazine clip - that drops out on the last shot being chambered - you will have a single-shot rifle. Gunboards.com has an entire forum dedicated to this rifle and its successors.
