John, you can see where Stan came up with the larger case than the current 6.8's buried in the quote from Guardsman26's: " Interestingly, US AMU stipulates that you need a case with a capacity of 40 grains of water to propel a 7g or 8g projectile so that it outperforms 7.62mm to 1,000 metres."
Although I am usually suspect of round numbers like "1,000 meters," it turns out that the range of the 7.62x54 weapons (like the PKM) is close to that. Joker31 wanted an MMG that would at least out shoot the PKM. The cartridges mentioned above should at least match the range of a PKM.
I do not want to start the definition wars again, so there would be a relatively lightweight MG for our dismounted troops that would match the range of the opposing 7.62x54 ones.
Although I may be misreading Joker's post, it seems that our 7.62x51 weapons do not match the 7.62x54's. I would imagine that this is why such things as the .338 Norma Mag have been mentioned. Whatever is used, I hope that it will not be hobbled by short ogive projectiles (like the 5.56, 7.62N, and even to some extent, the 338 LM).
