The .308 Norma Magnum was superseded in popularity by a firearm that was released in what year?
.308 Norma Magnum The .308 Norma Magnum (7.62×65mmBR) cartridge was created by Nils Kvale at Norma, Sweden. Like the larger .358 Norma Magnum it is based on the .300 H&H Magnum. The length of the case is the longest that would fit in a standard Mauser action. While it appeared to have a bright future initially, it was soon superseded in popularity by the .300 Winchester Magnum. The first, and one of the few, manufacturers to offer rifles in .308 Norma Magnum was Schultz & Larsen of Denmark and they still are.
M13 link The M13 link, formally Link, M13, is the U.S. military designation for a disintegrating metallic link specifically designed for belt-fed firearms and rounds; it was introduced in the mid-20th century. It is the primary link type for the U.S., and among NATO for the 7.62×51mm cartridge. It has been in use for over 50 years as of 2007 and is used on the Dillon M134D Minigun, M60 Machine Gun, FN MAG, AA-52, HK21, and the MG3, among others.
