13.2×99mm Hotchkiss Long
Heavy machine gun cartridge / From Wikipedia, the free encyclopedia
The 13.2 × 99 mm Hotchkiss Long (also known as: 13.2 Mle. 1930, 13.2 Breda, 13.2 Japanese, etc), is a heavy machine gun cartridge developed by France during the interwar period for the Hotchkiss 13.2 mm machine gun.[1] It saw major use as a heavy machine gun cartridge from the 1930s throughout WWII by a variety of nations due to the export success of the 13.2 mm Hotchkiss machine gun, but was eventually superseded in popularity by the 12.7 × 99 mm Browning (.50 BMG) after the war and eventually disappeared once the Browning cartridge became NATO standard.[2]
