development
Remington introduced the cartridge in 1999. The .300 Remington Ultra Magnum is based on the .404 Jeffrey case and does not require a belt. Due to the steep shoulder of the case and an almost cylindrical shape, the volume for the propellant powder could be increased, which benefited the speed of the cartridge.
