History

Introduced by Remington in 2002 as part of their Short Action Ultra Mag family. Largely overlooked during the .30-caliber and 6.5mm precision rifle era. The 2022 PRS scene's enthusiasm for 7mm bullets (driven by the 7mm PRC launch) created renewed interest in the 7mm SAUM as a short-action alternative.
