Yet they produce much less recoil than .308 or 30-06, and much better balistics than 5.56mm or 7.62x39mm, both of which are commonly criticized as being 300m or less rounds as far as being able to hit much of anything, let alone do much damage at that range.

It also doesn't make sense for me for the US Army to be looking at a new basically high power 6.8mm round when 7.62mm NATO can do basically everything they're looking for.

So what would work best? Trying to make a round (or even take one from the past) that's between 5.56mm and 7.62x39mm and 7.62mm NATO in performance, or just either pud-load the .308 or use a rifle with a muzzle brake/compensator for full auto or rapid semi-auto fire?

It should be noted that even .280 British can't fit in a AR-15 or AK-47/74 sized action since the max length of those round for those actions is like 57.5mm. .280 British is 64.5-65mm long, so you'd need basically an AR-10 sized action.
