I thought that this should be added to the 7mm cartridge group of wildcats, that became adopted, only this time it was military.
In the early 7,62mm NATO cartridge case designs and before the 7,62x51mm was adopted,
the BelgiumFN Factory took the early American 7,62x49 case and necked it down to 7mm. FN used the Mauser S12 bullet at 140 grs with a 2750 fps velocity.
Venezuela purchased 5000 new FN FAL rifles chambered for this 7x49mm cartridge called the 7x49 Liviano in 1954 and used these FAL rifles until 1961.
Also of interest, the 7mm-08 Remington introduced in 1980 which is the 308 Win necked down to 7mm loaded with a 140 gr bullet at 2860 fps
