There is A LOT you don't understand about external ballistics; first of all higher velocity rounds do not go straight through the target, they tumble, causing more trauma, and higher velocities result in more tumbling. The standard US military loading produces cavities of about 6" in diameter and the bullets fragment, which causes a lot of trauma. The 6.8mm and 6.5mm rounds have a larger permanent cavity, but that is at the cost of controllability and ammunition capacity, and the need for better stopping power is really less important than people think it is, also shown in the last document I provided.
For an improvement to weapons, I think the military should investigate duplex rounds again or an-94 (2 round burst) types weapons, because those systems improve a soldier's hit rate.
