Coyote thats the thing about this round I found interesting.  It performs as well as if not better in a shorter piece of brass. 
6.5, if the Marines start using it, well...   .45-70, 30-06, .308, .223, .45Colt, .45ACP...  I think you can see what I 'm getting at.
Nomo, YEAH!  Great ballistics!  Everything I've read has amazing results for performance all the way down range.  A lot of rounds peter off fairly quickly in either energy or velosity or both.  This one seems to hold up well in both.
