7mm RSAUM (Remington Short Action Ultra Magnum)
Remington introduced the 7mm Short Action Ultra Magnum cartridge in 2002 to compete with the 7mm Winchester Short Magnum cartridge. It was designed specifically for the Remington Model Seven Magnum rifle, and intended primarily for long-range hunting use. The difference in velocity between the 7mm SAUM cartridge and the 7mm WSM is less than 50 FPS; they're almost ballistic twins.
