6.5 Grendel Would Be my first choice; Think Howa or CZ527. Surprised no one has mentioned the 7.62x39 & 300 Black out. CZ 527 American would be my 1st choice in any of the calibers encouraged here.

If you are able to put a suppressor on the rifle then the 300 BLK may be your preferred choice for the job at hand. If you are not suppressing the firearm then a longer barrel should get serious consideration IMHO.

If 400 yards is likely to come into play much then I would go back to the 6.5 Grendel. http://www.65grendel.com/forum/showthread.php?15423-Howa-hb-threaded-grendel
