early FN FAL cartridge 7mm Liviano

[RCS]

Back when different cartridges were being tested for NATO adoption, the engineers at FN in Belgium developed an interesting cartridge. They took the US 7,62x49mm FATE1 case and necked it down to use the 7mm Mauser S12 bullet. This cartridge was adopted by Venezuela and called the 7x49 Liviano and FN sold them 3000 new FN FAL rifles chambering this cartridge in 1954.

the 7x49 Liviano fired a 7mm bullet at 2750 fps and there was also a AP cartridge

There was also a 7mm/T65 cartridge which was the 7,62x51 necked down to 7mm and called the "compromise"

7mm Mauser performance from an FAL. I think they had it right. Too bad Studler was a NIH idiot.

Actually a pretty common round in the US. Not sure what happened to the rifles, but lots of surplus ammo arrived in the US...with nothing to shoot them!

7mm Liviano / 7mm-08?

.280-30 / .30 BR?

in a vaguely similar vein:

.276 Pederson / 6.8SPC?
