This cartridge is also listed as the 11.15x59.8 Schuler. It is nothing more then a rimless, smokeless powder version of the popular German 11mm Model-71 Mauser military round. The case has a rebated rim (of smaller diameter then the body), to fit the standard 98 Mauser bolt face. The original cartridge could be not be stepped up very much in performance because the Models 71 and 71/84 where black powder rifles. The 11.2x60mm was chambered in the stronger Model 98 action. Although it is a considerable improvement over the old black powder 11 mm military round, it did not catch on in Africa. Most hunters there considered the bullet design unreliable for maximum penetration. In power, it is between the 405 Winchester and the 375 H&H; Magnum.
