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 Winchester Short Magnum (WSM) is less than 50 feet per second; they are almost ballistic twins.
Both the 7mm SAUM and the 7mm WSM achieve optimal ballistic results when using bullet weights from 120 to 160 grains.
The 7mm SAUM is a popular choice in f-class shooting, and has been used to take home multiple championships in this discipline.
The 7mm SAUM also fills a niche in extended long range competitions (700-2100 yards) where it is a popular choice.
