7 mm Cartridge

The 7mm is a member of the belted magnum family, who’s purpose was to provide headspace control while easing cartridge extraction. This makes it a desirable choice for hunting dangerous game. It is a popular choice on the Western plains of the US, as well as for use on plains game in Africa.
