History: Introduced by Remington in 1978 for the Model 700 BDL. The cartridge offered 8mm performance exceeding European standards and was aimed at elk and moose hunters wanting more power than .30 caliber magnums. Limited factory ammunition selection has constrained popularity, but handloaders appreciate the combination of the large case and quality 8mm bullets from European manufacturers.
