Introduced in 1999, it is based on the 9.3×64mm Brenneke case, necked up to accept a 0.375 in mm on diameter bullet. The case is also shortened by about 4 mm on to fit a standard length rifle action. It was developed as an evolution of Jeff Cooper's "Super Scout" medium rifle concept, which was in turn an extension of his original scout rifle concept. Cooper used a version of Steyr's Scout rifle chambered in .350 Remington Magnum to hunt large and dangerous game, originally calling it a "Super Scout". After taking a lion at close range with the weapon, he switched to calling that rifle his "Lion Scout". An additional motivation for development of the new cartridge was that authorities in certain areas of the world dictate a minimum rifle caliber, which may be used for hunting dangerous game, such as cape buffalo and lion. In general the minimum caliber needed is either .366 inch (9.3 mm) or .375 inch (9.5 mm), so that the majority of African countries will accept the newly designed cartridge, it uses a .375 inch (9.5 mm) caliber. When Steyr initially discussed the new round with Cooper, they intended to call it the .375 Steyr. Cooper said they should instead call it a .376, to avoid confusion with the .375 H&H Magnum. Cooper subsequently referred to the Scout Rifle in .376 Steyr caliber as the "Dragoon" or "Dragoon Scout," this marking being on the one that Steyr sent him. This designation has been dropped, and is not on production units. With a higher felt recoil, the .376 Steyr is the largest practical cartridge for use in such a short, lightweight weapon as the Scout. Steyr Mannlicher has also produced a conventional-style rifle to use this cartridge, dubbed the "Pro Hunter."
