Didn't Chuck Taylor play with with 6.5/.223 wildcat in an ar back in the 80's? 6.5 TCU? I always liked the 6.5's. right in the middle of 30 cal and .223. When the 6.8 came out I wondered why they didn't go with a 6.5/223 just to avoid mag issues.

The 6.5mm PCC is a modified 6.5 TCU for the AR Rifle platform.

Tag for interest. Nice work.

Wikpedia has that explained. They went with the 30 remington case for more powder for terminal perfomance, not target performance. The 6.8 has 80% of the power of the 308 in a lighter platform than the 308. Extremely popular gun in the pig infested states.

This would be interesting in a CZ 527, and very easy to do since its a .223 based action. Of course so would a grendel with the 7.62x39 version.

This round would do even better in a CZ-527 action, as there would
not be such a restrictive magazine length Issue as In the AR-15 platform...

I would predict it would match or even exceed Grendelballistics. It would also
have the ability to safely run at higher pressures...

Well you would be restricted by the magazine on the CZ.
