I'm assuming this is the new military round everyone is talking about.

Interesting....

something to keep an eye on.

I'm confused. I can't find any info on this such as parent case, (CZech?) ballistics, or reloading data. I might be interested. Is this a 270 caliber job? Ballistics anywhere near the 276 Pederson or 6mm SAW?

As posted on AR15.com, from a 16.5" barrel, MV is 2650fps for the 110gr bullet.

Neat. Bigger bullets are better bullets.

[Bulletbarn@charter.net]

Have you any reloading data on the 6.8mm SPC for projectile smaller then the 110 gr? I am a new member as of 4/11/08.

[Zak Smith]

I've loaded the 90's. Just add more powder.

[timberwolfEMT]

Bulletbarn, I have the reloading page from sierra on the 6.8mm spc the smallest bullet it has reloading data for is 90gr.

it is a .30 remington case shortened slightly and a new shoulder and it was necked down to a .270 caliber

PM me if you want me to send you the reloading page.
