The 8x50mmR Mannlicher is a rimmed rifle cartridge developed in the late 19th century, primarily for use in military firearms. It features a bullet diameter of 8mm and a case length of 50mm, making it suitable for various applications, including hunting and military use. The cartridge was notably used in the Mannlicher M1888 rifle, which was adopted by several European armies. This cartridge is known for its moderate recoil and effective range, making it a popular choice among hunters and sport shooters. The 8x50mmR Mannlicher has largely been replaced by more modern cartridges but remains a historical example of early 20th-century firearm technology.
