History

Developed in 2003 to circumvent European regulations prohibiting civilian ownership of military-caliber ammunition. By changing dimensions slightly from .50 BMG, it became legally distinct. Popular in France and other European countries with .50 BMG restrictions. Ballistically very similar to .50 BMG. Allows European shooters and manufacturers to work with .50-caliber-class cartridges legally.
