What types of guns take 7mm bullets?

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 third most popular, behind only the .308 itself and the .243 Winchester.[1] 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.
