Berger 150 @ .531
Hornady interbond or SSt @ .525
pretty close
If Lapua ever makes a scenar in .277 that will certainly be over .600
What else you got?
Not that I need a justification, but velocity. How fast can you run the bullet that lags by 0.070?
Lapua does make a 123 Scenar for the 6.5 that has a similar BC to the rounds you listed, I can run it well over 3200.
