7.62x39 is a decent round (AK 47)
7.62x51 is more powerful (Nato)
A .308 is even more powerful
H&K has their HK433 but that is is a 5.56
Very good gun.
They have planned variants of HK231 and HK123
If they’d build the HK123 to handle a .308, that would be best, as you could fire a 7.62x51 in a .308 gun, but NOT visa versa
Do you arm your guys with the inferior, but battlefield plentiful AK round?
Or do you give them a plentiful, more powerful round?
A .308 gun allows use of the common 7.62 Nato round, that a lot of our allies might carry (if not carrying the 5.56)
But would not allow scavenging from adversaries using AK’s like those being used in the ME
I think you have the power of the NATO and 308 flipped? NATO uses high pressures than 308. Do not shoot NATO in non-NATO capable 308 rifle.
