How could or should the 6.5 mm Grendel be improved?

[Howitzer]

My question is a very simple one: how should the 6.5 mm Grendel be improved. You're saying it's fine as it is. Fair enough, but so far no NATO or Western Army has adopted it. And it's been around for quite a while. What you achieved with the Grendel is amazing. I'm definitely a fan. I believe it deserves a wider audience, that's why I started this thread.

This statement really bothers me.. No nation has adopted it so it isn't the best cartridge available is that what you are insinuating? Simply because nobody is using it doesn't mean it isn't the best thing available, and I certainly wouldn't want to be on the opposing end of another nation using the Grendel. It is obvious that there are a lot of politics going on in these decisions and not all of them have the Soldiers best interest because if that was the case please tell me why they would choose the ACU pattern and why we are still wearing it.

Is the Grendel a 7.62? No. But it is best performing AR-15 cartridge available. If it was adopted I bet we would see a lot more expert marksmanship badges on our dress uniforms.

How can it be improved? Don't use Wolf Soft Point ammunition.
