AMU testing 6.5 based on Carcano case

[BluntForceTrauma]

You're welcome, John. BTW, "BluntForceTrauma"? Are you trying to tell us something?

Yes, that sometimes the truth hurts!

I found it interesting that case shoulder angle is the same as on the old .30-06 cartridge. I would've expected them to not use the steep, bench rest shoulder of the Grendel, but I'm quite surprised to see them revert to such a shallow angle. Shows an emphasis on feeding/chambering reliability?

Nope, shows an emphasis on play-it-safe, think-inside-the-box approach. All they're losing is "free" case capacity.

To be fair, 6.5 Grendel can't deliver the desired ballistics from the shorter barrels currently favored

Most "desired ballistics" are completely arbitrary, pulled from someone's nether regions to suit some particular whim or fancy. But, hey, when it's a general's arbitrary whim, none of us gets to argue.

The moment you say, "Here's an off-the-shelf with 2600 fps," they'll say, "Nope, we absolutely and unarguably MUST have 2650 fps." The moment you say, "Here's an off-the-shelf that penetrates 16.5 inches," they'll say, "Nope, we absolutely MUST have 16.75 inches. And, oh yes, another $22 million development costs and three more years of employment for all of us to study the issue."

I'm just happy they're s-l-o-w-l-y headed in the right direction. They'll finally climb this Mt. Everest, plant their flag and take their selfie photos, and then they'll notice us already there, lounging around eating crackers and cheese: "Hello, what took you guys so long?"
