7mm-08 Remington

The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length. Of cartridges based upon the .308, it is the second most popular behind only the .243 Winchester. However, the .308 is more popular than both. In 1980, the Remington Arms company popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles, along with a limited-run series within their Model 7600 pump-action rifles during the early 2000s.
