Mt Al,
This is worthy of a whole new thread. Since the 11.15x60R was the first of the officially adopted German centerfire cartridges, a great many cartridges during the following years were based on its case in different calibers. The lack of markings or markings that are not well understood makes reliable identification of the cartridge very difficult. This is compounded by the fact that these cartridges were introduced during a time protocols concerning bullet to barrel diameters were being established and were different than those in use today. You can be sure that, in the end, you can find cases and bullets that will work but may have to name it yourself. This is not as bad as it sounds, since you won't have to match your rifle to any available ammunition.
