Right, it's basically a .270 WSM. I'm not sure how this makes it a battle rifle class ammo or gain the ability to outpenetrate the 30.06 AP round.Moving a conversation here as it’s is less to do with that subject matter of the QST-11
First, a tungsten cored 30.06 would likely Penetrate a Chinese, Russian or American Level IV plate.

Now Carl and Ian know better they keep saying that M855A1 and M80A1 are Tungsten cores. They aren’t.
They are hardened steel core copper jacketed.
M80A1 Steel cored did not penetrate the plate they tested against. However M61 which is an AP round with a tungsten core and 7.62x51MM NATO did.
7.62x51mm was designed to match 30.06 and the standard for the Level IV rating is to defeat a M2 Hardened steel cored 30.06 round not a more exotic cored round. So beating M2 is like beating M80A1 only less copper more lead. But if you put an M61 projectile in a 30.06 case and shot it at a Level IV plate it would penetrate.
If this was 6.8x43mm SPC I would say you @Iron Man were absolutely correct that 7.62x51 or 30.06 would easily out perform. However the 6.8mm projectile being pushed by the US Army IS NOT SPC!
In a conventional cased configuration the weapons that have been built for this are based off 7.62x51mm parents. View attachment 53617
The round has characteristics on par with .270 Winchester short magnum, in a metric conversion that would be about 7x63mm.
This is part of why the weapon program is controversial among defense watchers. The round is almost identical in size.

The silvery round on the right is a 6.8mm conventional case version. The other rounds? 7.62x51mm sits next to it the other is 5.56x45mm NATO. So with this in mind we are talking about a battle rifle class ammo.
On a side note US SOCOM has started adopting 6.5mm Creadmore ammo for its battle rifle and Mk48 Mgs it gives higher range than 7.62x51mm a flatter trajectory and less felt recoil. The US Army may be trying to get the same here.
In the XM1186 configuration it is unlikely to penetrate Level IV ceramic plates as the core is steel.
However the XM1184 is called “Special Purpose” it could be an AP round with a tungsten core which should AP Level IV armor.
