The concerns was that making the core out of copper would make the rounds too expensive. Wonder why not steel?
The other question would be if the 6.5 Grendel would not be acceptable then what would be acceptable? It is clear that we are not going back to the 7.62x51 and that the 5.56x45 is just too light for many missions. While I think that the 6.5mm would be the ideal caliber, some might see that something closer to 7mm would be better. The question is how to get the maximum BC and sectional density so that the round puts more energy down range (.30 caliber rounds lose too much).
Then is what the dimenisions of the case should be. It appears that it should be close to 10.7mm in diameter. And no shorter than 40mm but not much longer than 45mm.
