.300 Remington Short Action Ultra Magnum (also known as 300 RSAUM, 300 RSUM or 300 Rem SAUM) is a .30 caliber short magnum cartridge that was put on the market shortly after Winchester released its 300 WSM round in 2001.[1]
Performance[]
The 300 RSAUM's ballistics are similar to 300 Win Mag and 300 WSM. The difference in ballistics between the WSM and RSAUM are fairly minuscule.
