Wm,
Welcome.
A couple of thoughts. You won't be competitive in long range BR (600 - 1,000M) with this calibre - it is too slow. All other things being equal the 6BR and Dashers will win at 600M and larger calibres at K. If the wind blows at all, your results will be even lower. Grendel was designed for short to intermediate range and specifically for an AR. Take it outside those parameters and it becomes its own handicap.
No offence but your current settup is probably incapable of 0.7MOA repeatable. No amount of ammo tinkering will shrink groups less than what the barrel is capable of. Popular recommendations for Olympic-grade barrels for the results you want are Krieger, Lilja and Bartlein - nothing else. If best groups at 600M is the goal I would upgrade the scope too. 2.5-25x50 is a good compromise range for hunting and target shooting with a 10x zoom ratio.
