Alternative to 6.5 Grendel?

[LRRPF52]

The problem with holding down COL to a minimum is that you are liable to end up without enough space to load long-ogive bullets. This problem affects the 5.56x45, 7.62x51 and even the .338 Lapua Magnum (which is why the .338 Norma Magnum was developed). This won't matter in short-range weapons but it surely does if you want a decent long-range performance.

Which is why you don't try to make a do-all weapon. Soldier's load and combat sustainment is more important than increased effective range all day long. A 1000m-capable 16" carbine is a total waste of resources in the hands of at least 50% of the combat arms soldiers in a light infantry platoon.

A 1000m-capable carbine in the hands of 6-8 of the more senior soldiers in a light infantry platoon would be a game-changer. Do we penalize the rest of them and the logistics system for those 6-8 soldiers?
