Remington introduced the 7mm Short Action Ultra Magnum cartridge in 2002 to compete with the 7 mm Winchester Short Magnum cartridge. It was designed specifically for the Remington Model Seven Magnum rifle. The difference in velocity between the 7mm SAUM cartridge and the 7mm Winchester Short Magnum is less than 50 feet per second, they are almost ballistic twins. This cartridge and the 7mm WSM have the most desireable ballistic results when using bullet weights from 120 to 160 grains.
