The Tankgewehr antitank rifle was developed by the Mauser company and adopted by the Imperial German military as an emergency measure to counter the introduction of tanks to the WW1 battlefield. The question is, did they really work? Could a 13.2mm AP bullet from a Tankgewehr really perforate the armor of a British tank? Well today we find out! The armor on a British tank was steel plate of 6mm, 8mm, and 12mm thickness, through-hardened to Brinell 440-480. We have replicated this with a plate of AR450 (ie, Brinell 450) armor, which we will be shooting at a distance of 50 yards. The ammunition we are using is original 1918 production German AP, and the rifle is a Tankgewehr captured by Allied troops late in the war and brought home as a souvenir.
