Just a thought here, but you could go to a .260 remington or 6.5-08. This will move you up to an AR10 platform, which will cost and weigh more, but based on my ballistic calculator the extra velocity will give you approximately 100ft-lbs more energy at 600 yards than the same bullet in the grendel. It could make the difference between a clean kill vs a wounded animal.
